All real numbers so the answer is D
You would do:
10.32/8 = 1.29
Therefore, the rate of cost per download is $1.29
The answer is 79 and 80.
x - the number of the first locker
x + 1 - the number of the consecutive locker
Their sum is 159.
x + x + 1 = 159
2x + 1 = 159
2x = 159 - 1
2x = 158
x = 158 / 2
x = 79
x - the number of the first locker: x = 79
x + 1 - the number of the consecutive locker x + 1 = 79 + 1 = 80
5/6 and 1/6 are exponents to X. The X’s are divided by each other. does that make sense?
