2(3x+4) - 2x = 24
I need help rq on this problem I need to solve it

x=4

Step-by-step explanation:

Given

2(3x+4)-2x=24

Expand parenthesis

6x+8-2x=24

Combine like terms

4x+8=24

Subtract 8 on both sides

4x+8-8=24-8

4x=16

Divide 4 on both sides

4x/4=16/4

x=4

Hope this helps!! :)

Please let me know if you have any questions

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64
