Answer:
5^ -7 =1 / 5^7
Step-by-step explanation:
(5^2)-^2/ 5^3
We know that a^b^c = a^(b*c)
(5^2)-^2 = 5^(2*-2) = 5^-4
5^-4/ 5^3
We know that a^b /a^c = a^ (b-c)
5 ^ (-4-3)
5^ -7
If we don't want to use negative exponents
We know that a^ -b = 1/ a^b
1 / 5^7
Answer:
x=1
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
When x = 1, it appears y is in between 1 and 2.
The only choice that satisfies this is B.
Let x be total amount traveled Therefore, x(.8333) = 90 x = 108 108 miles
hope i helped
7x+2y=48
7x+2(3)=48
7x+6=48
Subtract 6 on both sides.
7x=42
divide 7 on both sides
x=6
