8p + 3q - 18 when p = 1/2 and q = 7

You are given that p is equal to 1/2 and q is equal to 7, so plug these values into p and q in the expression to find your answer.

Rewrite your expression to include the values of p and q plugged in. Your expression should look like:

8(1/2) + 3(7) - 18

According to PEMDAS, multiplication should be solved first before doing subtraction, so multiply 8 by 1/2 and 3 by 7. Rewrite your expression; your expression should look like this:

4 + 21 - 18

According to PEMDAS, addition and subtraction should be solved from left to right; they are not prioritized. So solve the expression from left to right and then you will have your answer.

4 + 21 = 25

25 - 18 = 7

Your answer is 7.

Hi! Can someone help me please.
Sati [7]

Answer:

27 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2  where c is the hypotenuse

We are given the diagonal, which is the hypotenuse and a leg

36^2 + b^2 = 45^2

Subtract 36^2 from each side

36^2 + b^2 - 36^2 = 45^2 - 36^2

b^2 = 45^2 - 36^2

     b^2 =2025-1296

          b^2 =729

Take the square root of each side

sqrt(b^2) = sqrt(729)

b =27
