x = 17
Step-by-step explanation:
(x-3)2 = 7
Divide both sides by two
(<u>x-3)2</u> = <u>7</u>
2 2
x-3= 31/2
x= 31/2-3
x= 1/2 or 0.5
Answer:
Your movie marathon will last 6 hours.
Step-by-step explanation:
This question can be solved using a rule of three.
Each movie lasts
hours. How much do 4 movies last?
So
1 movie - 1.5 hours
4 movies - x hours
x = 4*1.5 = 6
Your movie marathon will last 6 hours.
Problem set A: A=6 and B=2
6=AxB^0 [6=6x1]
24=AxB^2= [24=6x2^2]
Problem set B: A=2 and B=4
32=AxB^2 [32=2x4^2]
128=AxB^3 [128=2x4^3]
