Kira runs a total of 144 miles in 9 weeks.
Step-by-step explanation:
Given,
Distance covered on Monday = 2.5 miles
Distance covered on Wednesday = 5.75 miles
Distance covered on Friday = 7.75 miles
Total distance covered per week = 2.5+5.75+7.75 = 16 miles
Total distance in 9 weeks = Distance per week * 9
Total distance in 9 weeks = 16*9 = 144 miles
Kira runs a total of 144 miles in 9 weeks.

As they vary from month to month, Luis's variable expenses are the utility bill, groceries, clothing and fuel.
Variable expenses is a concept in economics. They are costs that change due to an increase or decrease in the production volume, such as raw material costs.
The variable cost in money is obtained by multiplying, starting from a certain cost, the variable cost in kind by the price of the variable factor. The curves of average variable cost and marginal variable cost are deduced from the curve of variable cost in money according to geometric relationships.
Therefore, as they vary from month to month, Luis's variable expenses are the utility bill, groceries, clothing and fuel.

Answer:
6.5
Step-by-step explanation:
The sum of all angles in a triangle are 180 degrees.
=> 10x -10 + 8x + 10x + 8 = 180
=> 28x -2 = 180
=> 28x = 182
=> x = 6.5
So, Angle A = 10 x 6.5 -10 = 65 - 10 = 55 degrees
Angle B = 8 x 6.5 = 52 degrees
Angle C = 10 x 6.5 + 8 = 65 + 8 = 73 degrees.
55 + 52 + 73 = 55 + 125 = 180 degrees
