A: an exterior angle is supplementary to the adjacent interior angle.
Letter A,
if you put 18 centimeters into the y variable, and multiply 30 by 1/6 you get 5, plus 13, it equals 18.
So 18=18 which makes the statement true.
Answer:
-720
Step-by-step explanation:
10x^3y^2 If x = -2 and y = -3
10 * (-2^3) * (-3^2)
10 * (-8) * (9) = -720
Remark
The average is found by adding the total miles and dividing by the total number of hours.
Average
total distance = 52 + 64 + 49
Total distance = 165 miles
Total time = 1 + 1 + 1 = 3 hours.
Average = total distance/ total time
Average = 165 / 3 = 55 miles per hour.
(2n - 9) - 5(-2.4n + 4) =
The first set of parentheses is unnecessary, so we just drop them.
= 2n - 9 - 5(-2.4n + 4)
Now we distribute -5 by the second set of parentheses. Each term in the parentehses is multiplied by -5.
= 2n - 9 + 12n - 20
Now we combine like terms.
= 2n + 12n - 9 - 20
= 14n - 29
