Answer:
3
Step-by-step explanation:
(x+4) ^ 1/3 = 7
We need to cube each side of the equation
(x+4) ^ 1/3 ^3= 7^3
x+4 = 343
Subtract 4 from each side
x+4-4 = 343-4
x = 339
The power raised on each side is 3
Next time, Shay, please include the instructions. I'm assuming that our job here is to determine the largest # of boxes of darts that can be purchased.
Shirt cost + x(box of darts cost) = Initial amount
$56 + x($6/box) = $80
Then 56 + 6x = 80, or 6x= 24, or x = 4. He can buy 4 boxes of darts.
The red arrows show that the lines are parallel, but using the stuff given you can make an equation.
its hard to explain without drawing but starting from the 60 if you can make a Z you will get alternate angles and that mean that the given equation MUST be equal to 60. So,
8x-4=60
8x=60+4
8x=64
x=64/8
x=8 (is your answer)
hope you understand
