2 time the tenth root of d to the seventh power
When powers are in fractions, the denominator is a root and the numerator is a power. "2 times" means that two will be multiplied to d after its exponents are solved; otherwise the statement would've been "the product of 2 and d to the seven tenths power."
.75x-14=-8
Use inverse operations to find x
Add 14 on both sides
.75x=6
divide by .75 on both sides
x=8

Answer:
28 minutes
Step-by-step explanation:
Speed = distance / time
Your speed is 1 lawn / 57 minutes. Your friend's speed is 1 lawn / 54 minutes. Working together, your combined speed is:
1/57 + 1/54
So the time it takes working together is:
Speed = distance / time
1/57 + 1/54 = 1 / t
t = 27.7 minutes
Rounded to the nearest whole number, it takes 28 minutes.
