What is 3x +99 2(8*3)= 135<br> what is x equal to?

Ivenika [448]

Answer: -4

Step-by-step explanation: I am guessing you meant ...99 + 2(8*3)...

3x + 99 + 2(8 x 3) = 135

3x + 99 + 2(24) = 135

3x + 99 +48 = 135

3x + 147 = 135

(3x + 147) - 147 = (135) - 147

3x = -12

(3x) ÷ 3 = (-12) ÷ 3

x = -4

Answer: 2.5

Step-by-step explanation:

y = rx

substitute numbers in and solve for r

y = 10

x = 4

then

10 = r4

r = 10/4 = 2.5

this works for all the other numbers and always gives r = 2.5
