Answer:
500
Step-by-step explanation:
Given: P = 150 - T where P is passenger cars and T is trucks
10P = 7T ⇔ P = [tex]\frac{7T}{10}[/tex]
Plug in equation 2 into equation 1:
[tex]\frac{7T}{10}[/tex] = 150 - T
Solving for T, we get 500
Answer:
There would be 500 passenger cars and 350 trucks.
Step-by-step explanation:
In order to find this, we need to create a system of equations. Start by making the number of passenger cars as x and the number of trucks at y. Now the first equation can be the difference of the two.
x - y = 150
The second equation can make use of the proportion. If we multiply by the opposites we'll get the difference of 0.
7x - 10y = 0
Now we multiply the first equation by -10 and add together to solve for x.
-10x + 10y = -1500
7x - 10y = 0
-------------------
-3x = -1500
x = 500
Now we can find the amount of trucks by using either equation.
x - y = 150
500 - y = 150
-y = -350
y = 350

Loren and Julie have different part-time jobs after school. They are both paid at a constant rate of dollars per hour. The tables bellow show Loren and Julie’s total income for work given amount of time.
How much money would Julie earn for working 16 hours?
Julie works 1/12 hours/dollars. Write one or two-sentence explanation of what this rate means use this rate to find how long it takes for Julie to earn $228
Julie would earn $12/h×16h=$192
This rate means that for each hour she works, she gets $12.
The general formula for calculating these types of problems is:
m = r × t,
where m marks the total amount of money, r marks the rate and t marks the time.
To find the time when
m = $228
r = $12/h,
t = m ÷ t = 228 ÷ 12 = 19 hours.
Julie's income for 16 hours is $192. Julie takes only 24 hours to earn $288. The rate is $12 for each hour.
What are ratio and proportion?A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.

slope intercept equation for (0,-4) and (4,1)
Answer:
y = (5/4)x - 4
Step-by-step explanation:
As we move from (0, -4) to (4, 1), x increases by 4 and y increases by 5.
Thus, the slope of the line segment connecting these two points is
m = rise / run = 5/4.
Subbing these knowns into the point-slope formula for the equation of a straight line, we get:
y - 1 = (5/4)(x - 4), or
y = (5/4)x - 5 + 1, or
y = (5/4)x - 4
Let's check this out. Determine whether or not (0, -4) satisfies the equation:
-4 = (5/4)(0) - 4
Yes, this is true; the equation is correct.

Complete the inequality statement. 14 ft ____ 4 1/2 yd.
ok if i am right their are 0.3333 yards in a foot so if their is 14 feet it would be 4.66667
so your answer would go to the 4 1/2
Answer:
14 ft > 4 1/2 yd.
Step-by-step explanation:
1 yard = 3 ft
so
4 1/2 yard = 4.5 x 3 = 13.5 ft so it's less then 14 ft or 14 ft is greater than 13.5 ft
answer
14 ft > 4 1/2 yd.
Select the best possible first step to solving the system by first eliminating the y variable. 4x − 5y = 4 3x 2y = −20 (1 point) Multiply the first equation by −2, and multiply the second equation by 5. Multiply the first equation by 2, and multiply the second equation by −5. Multiply the first equation by 2, and multiply the second equation by 5. None of the above
Answer:
C) Multiply the first equation by 2, and multiply the second equation by 5.
Step-by-step explanation:
Given equations are :
4x − 5y = 4
and
3x+2y = −20
Now we need to select the best possible first step to solving the system by first eliminating the y variable. Where given choices of the possible steps are:
A) Multiply the first equation by −2, and multiply the second equation by 5.
B) Multiply the first equation by 2, and multiply the second equation by −5.
C) Multiply the first equation by 2, and multiply the second equation by 5.
D) None of the above
Since we need to eliminate y, then we must make coefficients of y equal in both equations. Easiest way is to multiply coefficient of first equation into 2nd equation and multiply coefficient of y from 2nd equation into first equation. Make sure that their sign is oppsite.
Hence correct choice is C)Multiply the first equation by 2, and multiply the second equation by 5.

According to the Pythagorean Theorem, a^2 + b^2 = c^2 where "a" and "b" are the two legs of the right triangle and "c" is the hypotenuse.
We are trying to find the part that is at an angle, which is "c". So if we know "a" is "3 and "b" is 4, we can plug the values into the equation.
3^2 + 4^2 = c^2 plug in the values
9 + 16 = c^2 simply the two squared values
25 = c^2 add the two values
5 = c take the square root of both sides
c = 5 switch the values

Answer:
48 X 3= 144 miles
Step-by-step explanation:
Answer:
144 miles
Step-by-step explanation:
First, let's use the distance formula which is distance = rate*time.
We know the rate is 48 miles and the time is 3 hours so if you were to plug it in to the formula you'd get distance = 48*3.
When you multiply 48 by 3 you get 144 which will be the distance.
What is the coefficient of the fifth term in (a+b)^9
Answer:
If you expand this using pascals triangle you will see that the fifth term is 126a^5b^4
the coefficient is the number 126
Answer:
The coefficient of the fifth term is 126.
Step-by-step explanation:
The question implies that after the expansion of [tex](a+b)^{9}[/tex], what would be the coefficient of the fifth term. This long expansion can be easily done by the application of the Pascal principle of expansion.
Thus,
[tex](a+b)^{9}[/tex] = [tex]a^{9}[/tex] + [tex]9a^{8}b[/tex] + [tex]36a^{7} b^{2}[/tex] + [tex]84a^{6}b^{3}[/tex] + [tex]126a^{5}b^{4}[/tex] + [tex]126a^{4} b^{5}[/tex] + [tex]84a^{3} b^{6}[/tex] + [tex]36a^{2} b^{7}[/tex] + [tex]9ab^{8}[/tex] + [tex]b^{9}[/tex]
So, from this expansion, the fifth term is [tex]126a^{5}b^{4}[/tex]. And its coefficient is 126.

Please solve this quick 8n+7=31
Hello there!
To find the value of n, work to isolate it from all other terms in the equation.
8n+7=31 - Start by subtracting 7 from both sides. 8n + 7 - 7 = 31 - 7
8n = 24 Next, divide both sides by 8 to finish isolating n. 8n÷8 = 24÷8
n = 3
This is your final answer.
I hope this was helpful and have a great rest of your day!
:)
For this case we must solve the following equation of first degree:
[tex]8n + 7 = 31[/tex]
We subtract "7" on both sides of the equation:
[tex]8n + 7-7 = 31-7\\8n = 24[/tex]
We divide between "8" on both sides of the equation:
[tex]\frac {8n} {8} = \frac {24} {8}\\n = 3[/tex]
Thus, the value of the variable n is 3.

the price c of a used car plus 8% sales tax
Answer:
1.08c or c + 0.08c
Step-by-step explanation:
The price of any used car plus 8% tax can be found by writing an expression. You can write an expression using a variable c where c is the price of the car. You will pay the 100% the whole price of the car and add on 8% of the price as tax. This means you pay 100 + 8 = 108% of the price c. This is 1.08c. Or you can also write it as c + 0.08c.

First you make the fractions have a common denominator. In this case it would be 6.
Then you have 8 3/6 - 2 4/6.
Because the number you are subtracting is greater than what you are subtracting from, you can turn the fraction into an improper fraction.
8 3/6 = 7 9/6
9/6 - 4/6 = 5/6
Then subtract the whole numbers.
