Diragio Lawn Care cuts 42 lawns every week. Each lawn uses 3 16 of a tank of gas when it is cut (on average). Part A: If the lawnmower had no gas at the start of the week, how many times would it be completely filled?

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

X= -5because this is a single step equation so you would just have to divide -16 both sides for x to equal your solution

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
