Question

Q = 5p + 3r
If p=6
And if r=-4
Work out the value of q.

Answer 1

18

Explanation:

q=5p + 3r. when p=6 and r=-4

substitute p and r into the equation

q= 5{6} + 3{-4}

q= 30 + {-12}

"+ * - = -"

so..... 30 -12 = 18

q = 18

Answer 2

Answer: q = 18

Explanation:

q=5p+3r, p=6, r=-4

First, let's plug in the numbers that we do know

q=5(6) + 3(-4)

Second, we should be able to figure the equation now that it is in simplified form.

q = 30 + (-12)

q = 18
