Answer:

Step-by-step explanation:


is the proportionality constant.

The
is the independent variable and
is the dependent variable.
The proportionality constant is
.
That will be 40 because the problem is making you multiple
15-t + 8t = -13
15 + 7t = -13
7t = -13-15
7t = -28
t = -4
4a + 11-a = 2
3a = 2-11
3a = -9
a = -3
The answer is 7 because the mean is an average. So if you add up all the numbers and then divide that number by the amount of numbers listed then that will get you your answer which is 7
4+5+6+7+8+9+10=49
49/7=7
I don’t know this answer but I think it’s 81
