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

Answer:

500

Step-by-step explanation:

Given: P = 150 - T where P is passenger cars and T is trucks

10P = 7T ⇔ P = \frac{7T}{10}

Plug in equation 2 into equation 1:

\frac{7T}{10} = 150 - T

Solving for T, we get 500

Which statement describes the graph?
max2010maxim [7]

Answer : D

From the given graph , we can see that

The graph crosses the y axis at 7

So y axis is (0,7)

The graph is increasing at first  and reaches (-2,8)  and then start  decreasing

The graph start increasing at x=-10  and goes on increasing till x= -2

then the graph start decreasing at x=-2  and goes in decreasing till x= 10

The graph crosses the y axis at (0,7), increasing from x=-10  to x=-2  and decreasing from x=-2 to x=10

Answer D is correct

What is the measure of angle x?
Kaylis [27]
Hello!

The total measure of the angles in a triangle always add up to 180 degrees. 

The measures that you are given are 37 and 82 degrees. To find what angle x equals, we must first add together the angles that we know:
37 + 82 = 119

To find angle x, we simply subtract 119 from the total number of degrees (180):
180-119 = 61

The measure of angle x is 61 degrees. 

I hope this helps you! Have a fantastic day!

6x + 3(x + 1.15) gfgfdgfdgdfgfdgfggfdgfdgfddfdfgdfgdf
madreJ [45]

Answer:

9x+3.45

Step-by-step explanation:

Let's simplify step-by-step.

6x+3(x+1.15)

Distribute:

=6x+(3)(x)+(3)(1.15)

=6x+3x+3.45

Combine Like Terms:

=6x+3x+3.45

=(6x+3x)+(3.45)

=9x+3.45
