Step-by-step explanation:
First, let's move all of the terms with an 
to the left-hand side of t he equation, and everything else to the right-hand side of the equation.
Next, let's divide both sides by 
to isolate the variable by itself on the left-hand side of the equation:
Answer:
129
Step-by-step explanation:
the sum of the interior angles of a quadrilateral is 360, so you add 71+112+48 and subtract it from 360 to get x
Answer = C because 5-4 and 5/6 - 3/6 = 1 and 2/6
Answer:
0% of the racers finished in 28 minutes or less
Step-by-step explanation:
There is the need to understand the meaning of the standard deviation in this question.
The <em>standard deviation expresses by how much the finishing time differed from the mean/average time</em>. So, it tells us that the time range for all of the racers can be written as Mean ± Standard Deviation = 32 ± 2 minutes = (32 - 2) to (32 + 2) = 30 to 34 minutes.
So, all of the racers finished in 30 minutes or more, and no one finished in less than thirty minutes.
The questions asked to know o those who finished in 28 minutes or less, and that does not exist in this given data, so 0% of the racers finished in 28 minutes or less
Answer:
A. 4 games
B. $31
Step-by-step explanation:
Fun guys game rental store:
5 + 6.50x
Game bank:
17 + 3.50x
Where,
x = number of games
For how many games rentals will the cost be the same at both stores?
Equate the charges of both stores
5 + 6.50x = 17 + 3.50x
5 - 17 = 3.50x - 6.50x
12 = 3x
Divide both sides by 3
x = 12/3
= 4
x = 4 games
What is that cost?
Game bank:
17 + 3.50x
= 17 + 3.50(4)
= 17 + 14
= $31
