Answer:
37/24
Step-by-step explanation:
Since the denomenators must be consistent, both 8 and 12 have the common factor of 24.
the denominator of 8 must be multiplied by 3 to get to 24, but to multiply the denominator you must multiply the numerator by 3 which gives you
15/24
the denominator of 12 must be multiplied by 2 to get 24, so you must multiply 11 by 2 as well to get
22/24
add them together to get 37/24
The area of a rectangle is its times its width where "A" represents the area, "L" represents the length and "W" represents the width
Answer:
The length will be letter C, 50 m
N = nickels and q = quarters
0.05n + 0.25q = 1.90
n = 2q + 3
0.05(2q + 3) + 0.25q = 1.90
0.10q + 0.15 + 0.25q = 1.90
0.10q + 0.25q = 1.90 - 0.15
0.35q = 1.75
q = 1.75/0.35
q = 5 ......there are 5 quarters
n = 2q + 3
n = 2(5) + 3
n = 10 + 3
n = 13 <=== there are 13 nickels
