Answer:
Step-by-step explanation:
x/2 = 2x-3
x = 4x-6
3x = 6
x = 2
Surface area of a cube is given by
SA=6a²
but
SA=150 in²
thus
150=6a²
solving for a we obtain:
150/6=a²
a²=25
thus
a=√25
a=5 inches
hence the side length is 5inches
-10,-12,-14,-16,-18......
Hey there!
The correct answer is 
~ Write the equation
~ Simplify
~ Subtract
from both sides
~ Subtract
from both sides
~ Divide both sides by 8
Hope it helps and have a great day!
Let julia's age be x
Let Kara's age be 4x
x+4x=13
5x=13
x=13/5
