80(miles) x 52(weeks in a year) = 4160(miles in a year)
4160 / 4(tunes in a year) = 1040(miles to go before a tune)
Now for Christine
100(miles) x 52(weeks in a year) = 5200(miles in a year)
5200 / 1040(miles to go before a tune) = 5(tunes in a year)
Answer C. 5
Answer:
-20x+30
Step-by-step explanation:
Here ya go. Hope I helped
A ^ 3b ^ -2 / ab ^ -4, a ≠ 0, b ≠ 0
First we rewrite the expression respecting the properties of the exponents.
b ^ -2 = 1 / b ^ 2
1 / b ^ -4 = b ^ 4
We have then:
a ^ 3b ^ -2 / ab ^ -4
a ^ 3b ^ 4 / ab ^ 2
answer:
An expression using positive exponents is
D a^3b^4/ab^2
