Answer:
x = 7.25
Step-by-step explanation:
First you must try to get the x by itself with the 4, so, you have to subtract 5 from both sides so that the five is no longer on the side of the variable. Once you do this the equation becomes 4x = 29. Then you have to get x by itself so you then have to divide the 4 on both sides and the answer it then x = 7.25

A. about 72.5 feet
B. about 145 feet
C. about 17 feet
D. about 24 feet
Answer:
C. about 17 feet
Step-by-step explanation:
Since, we know that,
The area of a square is,
[tex]A=s^2[/tex]
Where,
s = side length,
If A = 290 square feet,
[tex]\implies 290 = s^2[/tex]
[tex]\implies s = \sqrt{290}=17.0294\approx 17[/tex]
Hence, the side length of the patio would be about 17 ft,

A garden table and a bench cost $804 combined the garden table costs $46 less than the bench. What is the cost of the bench
Answer:
The cost of the bench is 425 dollars.
Step-by-step explanation:
Let x represent the garden table.
Let y represent the bench.
x + y = 804
x = y - 46
Use the substitution method.
y - 46 + y = 804
2y - 46 = 804
Add 46 to both sides.
2y = 850
Divide both sides by 2.
y = 425
Answer:
The cost of the bench is 425 dollars.
The sum of the speeds of two trains is 719.1 miles per hour. If the speed of the first train is 6.9 mph faster than that of the second train, find the speeds of each. What is the speed of the first train? nothing ▼ miles per hours (Type an integer or a decimal.) What is the speed of the second train? nothing ▼ hours miles per hour miles (Type an integer or a decimal.)
Answers
First train's speed is 363 mph
Second train's speed is 356.1 mph
=====================================
Explanation:
x = speed of first train, y = speed of second train
x+y = 719.1 because the two speeds add to this value (sum means result of addition)
x = y+6.9 due to the fact that the first train (x) is faster than the second train (y) by 6.9 mph
Use substitution to find that...
x+y = 719.1
y+6.9+y = 719.1 <--- replace x with y+6.9
2y+6.9 = 719.1
2y = 719.1-6.9 <--- subtract 6.9 from both sides
2y = 712.2
y = 712.2/2 <--- divide both sides by 2
y = 356.1
now use this y value to find x
x = y+6.9
x = 356.1+6.9
x = 363
The speed of the first train is 363 mph and the speed of the second train is 356.1 mph. To find these, we solved the equation 2x + 6.9 = 719.1, where x represents the speed of the slower train.
To solve this problem, we will use algebra to set up equations based on the information given. Let's denote the speed of the second train as x miles per hour. Accordingly, the speed of the first train is described as x + 6.9 miles per hour, since we are told it is 6.9 mph faster than the second train. The sum of their speeds is given to be 719.1 mph. Therefore, we can write the following equation to find the speeds of each train:
x + (x + 6.9) = 719.12x + 6.9 = 719.12x = 719.1 - 6.92x = 712.2x = 356.1Hence, the speed of the second train is 356.1 mph. Now to find the speed of the first train we add 6.9 mph to the speed of the second train:
Speed of the first train = 356.1 mph + 6.9 mphSpeed of the first train = 363 mphSo the speed of the first train is 363 mph, and the speed of the second train is 356.1 mph.
A car dealer earns a 4% commission on all cars sold. Last month, he earned $7,200 in commission. He wants to earn $8,000 in commission this month. What increase in total sales does he need in order to reach his goal for this month?
Answer:
$800 is the answer because you subtract 7200 from 8000 and you get 800
Final answer:
To earn an $8,000 commission at a rate of 4%, the car dealer needs to increase his total sales by $20,000, from $180,000 last month to $200,000 this month.
Explanation:
The car dealer wishes to increase his commission from $7,200 to $8,000. Since he earns a 4% commission on all cars sold, we first need to determine how much his sales were last month. To do this, we divide his commission for the last month by the commission rate:
Last month's sales = Commission / Commission rate = $7,200 / 0.04 = $180,000
To earn $8,000 this month, we need to find the total sales required:
This month's sales = Desired commission / Commission rate = $8,000 / 0.04 = $200,000
To find the increase in total sales needed, we subtract last month's sales from this month's sales target:
Required increase in sales = This month's sales - Last month's sales = $200,000 - $180,000 = $20,000

Can someone give me the answers for these?
Answer:
a. He started with $50 in the the account.
b. The account grow by $10 dollars each week
c see graph
Step-by-step explanation:
y = 50 + 10x
We can rewrite this as
y = 10x+50
This is in the form y = mx+b
where m = 10 which is the slope and b =50 which is the y intercept
The y intercept = 50 is the starting value or the value when x = 0
a. He started with $50 in the the account.
The slope is how much it grows by as x grows. As x increase by 1 , y will grow by the slope or 10, so the account will grow by 10 each week.
b. The account grow by $10 dollars each week
c see graph

Simplify your answer as much as possible.
Answer:
u ≤ 4
Step-by-step explanation:
The given inequality
15 ≤ 39 - 6u
Subtract 39 from both sides, we get
15 - 39 ≤ 39 - 6u - 39
-24 ≤ -6u
Dividing both sides by -6, we get
4 ≥ u [Remember, when we divide by negative, the direction of
the inequality changes]
Which is u ≤ 4.

We will use the FOIL technique to multiply the terms.
First: 2x*x = 2x^2
Outer: 2x* -4 = -8x
Inner: 3*x = 3x
Last = 3* -4 = -12
Add the 4 terms together: 2x^2 -8x+3x -12 = 2x^2 -5x-12
Area = 2x^2 -5x-12
Answer: 2x^2 - 5x - 12
Step-by-step explanation: The correct answer is 2x^2 - 5x - 12. To find the area of a rectangle you multiply the length by the width. So you multiply (2x + 3)(x - 4) using the FOIL method.

5. Your brother has $2,000 saved for a vacation. His airplane ticket is $637. Write and solve an inequality to find out how much he can spend for everything else.
Answer:
2000>= 637+ x
1363>= x
He can spend no more than $1363 on everything else
Step-by-step explanation:
If he has 2000 dollars to spend in total, that will go on one side of the inequality. Everything he spends goes on the other. 2000 is the maximum he can spend. He is going to sped 637 on an airline ticket plus x on other expenses.
2000>= 637+ x
Subtract 637 from each side
2000-637 >= 637-637 +x
1363>= x
To find out how much your brother can spend for everything else, subtract the cost of the airplane ticket from his total savings. Your brother can spend up to $1,363 for everything else.
To find out how much your brother can spend for everything else, we need to subtract the cost of the airplane ticket from his total savings. Let's say his total savings is $2,000 and the cost of the airplane ticket is $637. We can write the inequality as:
2000 - 637 ≤ x
Simplifying the inequality, we have:
1363 ≤ x
Therefore, your brother can spend up to $1,363 for everything else.

Point E is the midpoint of side BC of parallelogram ABCD (labeled counterclockwise) and AE ∩ BD =F. Find the area of ABCD if the area of △BEF is 3 cm2.
Answer: [tex]36 cm^2[/tex]
Explanation:
Since here ABCD is the parallelogram.
Where E is the mid point of the line segment BC.
And, F is the intersection point of the segments AE and BD,
Also, Area of △BEF is 3 [tex]cm^2[/tex].
We have to find Area of parallelogram ABCD.
Since,In ΔBEF and ΔACD,
∠ADF=∠EBF ( because AD ║ BE )
∠DFA = ∠BFE (vertically opposite angle)
Thus, By AA similarity postulate,
[tex]\triangle BEF \sim \triangle ACD[/tex],
Thus, [tex]\frac{area of \triangle ADF }{area of \triangle BFE} =(\frac{AD}{BE})^2[/tex]
But, AD = 2 BE,
Therefore, [tex]\frac{area of \triangle ADF }{area of \triangle BFE} =(\frac{2BE}{BE})^2[/tex] = 4/1
Thus, area of Δ ADF = [tex]12 cm^2[/tex]
Similarly, [tex]\triangle ADB \sim \triangle BAE[/tex]
Now, let the area of the triangle AFB = x [tex]cm^2[/tex]
Thus, x + 12 = 2(x+3) ( because the area of the ΔADB = 2(area of ΔBAE) )
⇒ x = 6 [tex]cm^2[/tex]
Therefore, area of ΔAFB= 6 [tex]cm^2[/tex]
⇒ area of ΔABD = 12 + 6 = 18 [tex]cm^2[/tex]
By the definition of diagonal of parallelogram,
Area of parallelogram ABCD = 2× area of Δ ABD= 2 × 18 = 36 [tex]cm^2[/tex]

Answer:
402.88mm³
Step-by-step explanation:
To find the answer to this, we need to find the total area of the coin and then the size of the inner coin.
As this is a cylinder, the formula is:
[tex]\pi r^{2} h[/tex]
So lets find the area of the whole coin.
The radius is 11.5 and height is 2.2
[tex]\pi * 11.5^{2} * 2.2 = 914.05[/tex]
Now, the area of the inner circle:
Radius is 8.6 and height is 2.2:
[tex]\pi * 8.6^{2} * 2.2 = 511.17[/tex]
Now to find the area of the silver ring in the coin, you subtract the inner circle measurement from the whole coin measurement:
914.05 - 511.17 = 402.88
So the volume of the outer ring is 402.88mm³
The first equation in the following system gives a company's income, in dollars, for selling x baseball caps. The second equation gives the cost of making x baseball caps. y = 8x y = -0.01 x2 + 4x + 3,200 The solution of the system is (400, 3,200). How would you interpret this solution?
Answer:
The solution of the system is the point where the graphs intersect, or have the same x and y values. This means that the company's cost to produce 400 caps is the same as the income made from selling 400 caps. Therefore, the company will not make a profit.
