Combine like terms.

3a + 2a = 5a

5a - 2b.

Plug in the values for a and b.

5(2) - 2(3)

10 - 6 = 4

Answer is B.

<em>Hello there, and thank you for asking your question here on brainly.

<u>Short answer: B. 4
</u>
Why? 

When we have an equation like 1x, and x = 2, then that means that we are multiplying by x or 1 * x. So, a = 2 and b = 3, we have to multiply 3 & 2 by 2, and 2 by b. (3 * a(2) ==> 6) ~~ (2 * 2 ==> 4) ~~ (2 * 3 ==> 6) Now, we have 6 - 6 + 4. Evalutate. (6 - 6 ==> 0) ~~ (0 + 4 ==> 4) <u>4 is the final answer.

</u>Hope this helped you!!! ♥<u>

Answer:

y = x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1, thus

y = x + c ← is the partial equation

To find c substitute (5, 3) into the partial equation

3 = 5 + c ⇒ c = 3 - 5 = - 2

y = x - 2 ← equation of line

The perimeter of a movie screen is 54 meters. The screen is 18 meters wide. How tall is it?
Roman55 [17]
Assuming the movie screen is rectangular, the answer would be 8 meters tall. Because the perimeter is 2 times width plus 2 times height, you can subtract 36 (18 times 2) from 54. This leaves you with 18, which is 2 times height. Divide both by two and you get 9
