Julio drives 2.5 hours at 45 miles per hour. Kilgore drives 4 hours at 35 miles per hour. Who drives farther? How much
farther?
Kilgore, 27.5 miles
Julio: 28.5 miles
Julio: 112.5 miles
Kilgore; 140 miles
Answers
Answer:
kilgore, 140 miles
Step-by-step explanation:
Kilgore drives farther than Julio with a difference of 27.5 miles. Julio drives 112.5 miles while Kilgore drives 140 miles.
To determine who drives farther, we need to calculate the distance driven by Julio and Kilgore.
Julio: Julio drives 2.5 hours at 45 miles per hour. Using the formula distance = speed × time, Julio's distance is 45 miles/hour × 2.5 hours = 112.5 miles.Kilgore: Kilgore drives 4 hours at 35 miles per hour. Applying the same formula, Kilgore's distance is 35 miles/hour × 4 hours = 140 miles.Kilgore drives farther. The difference in the distance is 140 miles - 112.5 miles = 27.5 miles.

solve for a 7a - 2b =5a + b
Answers
Answer:
a = 3/2 b
Step-by-step explanation:
7a - 2b =5a + b
Subtract 5a from each side
7a-5a - 2b =5a-5a + b
2a -2b = b
Add 2b to each side
2a-2b+2b = b+2b
2a = 3b
Divide each side by 2
2a/2 = 3b/2
a = 3/2 b

we have been given an expression [tex]\frac{\frac{2}{3}}{-4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]. We are asked to simplify our given expression.
Using quotient rule [tex]\frac{\frac{a}{b}}{c}=\frac{a}{bc}[/tex], we will get:
[tex]\frac{2}{3\cdot -4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]
[tex]\frac{2}{-12}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]

[tex]\frac{2}{-12}-\left(\frac{-7}{6}\right)[/tex]
[tex]-\frac{2}{12}+\frac{7}{6}[/tex]

Solve the system of equations :
2x -5y=-22
X+7y=27
Answers
Answer:
x=−1 y=4
Step-by-step explanation:
Let's solve your system by substitution.
2x−5y=−22; x+7y=27
Rewrite equations:
x+7y=27;2x−5y=−22
Step: Solve x+7y=27for x:
x+7y=27
x+7y+−7y=27+−7y(Add -7y to both sides)
x=−7y+27
Step: Substitute−7y+27 for x in 2x−5y=−22:
2x−5y=−22
2(−7y+27)−5y=−22
−19y+54=−22(Simplify both sides of the equation)
−19y+54+−54=−22+−54(Add -54 to both sides)
−19y=−76
−19y
−19
=
−76
−19
(Divide both sides by -19)
y=4
Step: Substitute 4 for y in x=−7y+27:
x=−7y+27
x=(−7)(4)+27
x=−1(Simplify both sides of the equation)

The height of a tree increases by 60% each year. When planted the tree was 40cm tall. How tall will the tree be in 5 years time.
Answers
Answer:
≈419.4 cm.
Step-by-step explanation:
To solve this problem, you will need to set up an exponential graph as shown:
y= 40 ·[tex](1.6)^{x}[/tex]
The 40 represents the initial height of the tree, while (1.6) represents the annual growth rate. 'x' represents the amount of years elapsed.
We can simply solve this by substituting 5 for x:
y= 40· [tex](1.6)^{5}[/tex]
y ≈ 419.4 cm.

Solve the system. -3x + 4y = -22 2x + 7y = 5 A) (6, -1) B) (-1, 6) C) (-6, 1) D) (-1, -6)
Answers
Answer:
A
Step-by-step explanation:
We have the system of equations:
-3x + 4y = -22
2x + 7y = 5
Let's solve this using elimination, so multiply the first equation by 2 and the second equation by 3:
2 * (-3x + 4y = -22) ⇒ -6x + 8y = -44
3 * (2x + 7y = 5) ⇒ 6x + 21y = 15
Our equations are now:
-6x + 8y = -44
6x + 21y = 15
Add these two together to eliminate the x term:
-6x + 8y = -44
+ 6x + 21y = 15
______________
0x + 29y = -29
y = -29/29 = -1
Plug this back into one of the equations to find x:
-3x + 4y = -22
-3x + 4 * (-1) = -22
-3x - 4 = -22
-3x = -18
x = -18/(-3) = 6
The answer is (6, -1) or A.
Answer:
A. (6,-1)
Step-by-step explanation:
-3x + 4y = -22
2x + 7y = 5
x = (5 - 7y)/2
-3[(5 - 7y)/2] + 4y = -22
-15/2 + 21y/2 + 4y = -22
29y/2 = -29/2
y = -1
x = (5 - 7(-1))/2
x = 12/2
x = 6
Joan receives a 9% commission on appliances she sells. Last month she sold $18,500 worth of appliances. How much did Joan earn in commissions last month?
Answers
Answer:
She earned $1,665.
Step-by-step explanation:
x / 18500 = 9/100
What did you do to transform 18500 into 100? Divide by 185
Since you divided the denominator 185, you must do the same to the numerator.
x / 185 = 9 OR 9 * 185 = x
x = 1665

Irina wants to build a fence around a rectangular vegetable garden so that it has a width of at least 10 feet. She can use a maximum of 150 feet of fencing. The system of inequalities that models the possible lengths, l, and widths, w, of her garden is shown. w ≥ 10 2l + 2w ≤ 150 On a coordinate plane, 2 solid straight lines are shown. The first line is horizontal to the y-axis at y = 10. Everything above the line is shaded. The second line has a negative slope and goes through (0, 75) and (75, 0). Everything to the left of the line is shaded. Which length and width are possible dimensions for the garden? l = 20 ft; w = 5 ft l = 20 ft; w = 10 ft l = 60 ft; w = 20 ft l = 55 ft; w = 30 ft
Answers
Answer:
In option a, w < 10
in option b, w = 10 and 2(20) + 2(10) = 40 + 20 = 60 < 150
in option c, w > 10 but 2(60) + 2(20) = 120 + 40 = 160 > 150
In option d, w > 10 but 2(55) + 2(30) = 110 + 60 = 170 > 150
Therefore the corect answer is option b.

After decoding the clues on the map, they found out that they needed to go to the
Island of Mysteries which was 120 miles away. To get there, they could either
take a plane for $600 or a boat for $254. How much money can they save if they
took a boat to the island?
Answers
Answer:
$346.00
Step-by-step explanation:
We know that the price to take a plane to the Island of Mysteries is $600 and the price to take a boat is $254.
To find how much money they will save if they were to take a boat, you would subtract the cost of the boat ride from the plane ride to find the difference.
$600 - $254 = $346.00

Answers
Answer: [tex]x=6[/tex]
Subtract 2x from both sides
[tex]8x-72-2x=2x-36-2x\\6x-72=-36[/tex]
Add 72 to both sides
[tex]6x-72+72=-36+72\\6x=36[/tex]
Divide both sides by 6
[tex]6x/6=36/6\\x=6[/tex]
Answer:
x=6
Step-by-step explanation:
first thing first you always need to get x alone and since you have an X on both side we need to move one of them to the same side as the other one.
8x-72=2x-36
add 72 on both sides ( the opposite of subtracting is adding)
8x=2x-36+72
8x=2x+36
then we subtract 2x on both sides to get X alone
8x-2x=36
6x=36
then we divide 36 by 6 to get our answer for x
X= 6
