Answer:
n=3
Step-by-step explanation:
8n + 2 = 5n + 11
Subtract 5n from each side
8n-5n + 2 = 5n-5n + 11
3n+2 = 11
Subtract 2 from each side
3n+2-2 = 11-2
3n = 9
Divide by 3
3n/3 = 9/3
n =3
Answer:
6^2+8^2=10^2
5^2+x^2=6^2
Step-by-step explanation:
Answer:
f(x)/3 = -x +7
Step-by-step explanation:
f(x)=-3x+21
To find f(x)/3 divide each side by 3
f(x)/3=-3x/3+21/3
f(x)/3 = -x +7
This kind of problem assumes that the two people working together work for the same amount of time.
Renee can sew a quilt in 16 hours, so she can sew 1/16 of a quilt each hour. Gerena sews a quilt in 12 hours, so she can sew 1/12 of a quilt each hour.
Use the variable t represent the time Renee and Gerena work together (measured in hours). The part of a quilt Renee sews is . the part of the quilt that Gerena sews is
Together, they sew one quilt, so
Multiply all the terms by 48 (the Least Common Multiple of 16 and 12).
hours.
