B is the answerr okkkkkkk
Answer:
1/3
Step-by-step explanation:
3^2/5 x 3^-7/5
We know that a^b* a^c = a^(b+c)
3^(2/5 -7/5)
3^ (-5/5) = 3^ -1
We know that a^-b = 1/ a^b
3^-1 = 1 / 3
5x = x^2 + 4
x^2 - 5x + 4 = 0
(x - 4)(x - 1) = 0
x = 4, 1
(x + 6)^2 = 100
x + 6 = +/1 sqrt100
x + 6 = +/- 10
x = 4, -16
One tenth is 0.1. Therefore, the answer has to be 2.x. Since 4 is less than 5, the 2 remains the same. The answer is 2.2.
Amount of hours worked = h
7h = 91
h = 13 hours worked that week
h (is greater to or equal to) 15
7 x 15 would equal 105 which means the most she can make in a week is $105
