It adds up to 180 degrees
Answer:
8 1/8
Step-by-step explanation:
V = 16 1/4 • 1/2
V = 8 1/8
Answer: 56
Step-by-step explanation:
4=(a+b-24)/2
32=a+b
32+24=56
Answer:
System of equations:
L = 5W + 7
2W + 2L = P
L = 62 cm
W = 11 cm
Step-by-step explanation:
Given the measurements and key words/phrases in the problem, we can set up two different equations that can be used to find both variables, length and width, of the rectangle.
The formula for perimeter of a rectangle is: 2W + 2L = P, where W = width and L = length. We also know that the L is '7 more than five times its width'. This can be written as: L = 5W + 7. Using this expression for the value of 'L', we can use the formula for perimeter and solve for width:
2W + 2(5W + 7) = 146
Distribute: 2W + 10W + 14 = 146
Combine like terms: 12W + 14 = 146
Subtract 14 from both sides: 12W + 14 - 14 = 146 - 14 or 12W = 132
Divide 12 by both sides: 12W/12 = 132/12 or W = 11
Put '11' in for W in the equation for 'L': L = 5(11) + 7 or L = 55 + 7 = 62.
Answer:
B. 
; 
Step-by-step explanation:
According to the statement, we find that the following two conditions must be observed:
(Eq. 1)
(Eq. 2)
Since the difference between two even numbers leads to another even number. Hence, 
must be an even number and the correct answer is B.
