(C) y = −8 ÷ 2; y = −4.
Step-by-step explanation: We are given to select the correct steps that shows the solution to the following equation :

We know that
the solution to the equation
is given by

Therefore, the solution of equation (i) is as follows :

Thus, (C) is the correct option.
Answer: d=7.5
Step-by-step explanation: 5.5=−2+d d−2+2=5.5+2 d=7.5
It will take 3 laps. 90*35=3150 1000 m = 1 km
Median is the middle number
60, 60, 65, 70, 70, 85, 90
70 is your median
mode is the number(s) that show up the most
60 and 70 is your mode, since they show up twice (one more than the others)
Range is largest number minus the smallest
90 - 60 = 30, 30 is your range
Mean is all the numbers added together divided by the number of numbers there are
60 + 90 + 65 + 70 + 70 + 85 + 60 = 500
500/7 = 71.42
Mean = 71.42
hope this helps
