Answer:
Oh cool! The answer is 90 since a and c or parallel, b cuts through them perpendicularly, forming a right angle.
Step-by-step explanation:
Answer:
v = -52
Step-by-step explanation:
Divide both sides by -5
v + 65 = 13
v = 13 - 65
v = -52
The value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90
<h3>How to evaluate the expression?</h3>
The expression is given as:
5x – 2y + (7x – y)
Substitute x = 7 and y = –2 in the above expression
5 * 7 - 2 * -2 + (7 * 7 + 2)
Evaluate the expression
90
Hence, the value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90

Add up the fractional amounts and divide them by however many amounts there are..........
eg.
Step 1:Add the fractions
1/6 + 5/8 +3/4
(find the LCD)
1/6 + 5/8 + 3/4 = 4/24 + 15/24 + 18/24 = 37/24
Step 2: Divide the sum by the number of numbers in the set
37/24 ÷ 3= 37/24 ÷ 3/1= 37/24 X 1/3= 37/72
<span>So the mean (average) is 37/72</span>
