Answer:
b = 
Step-by-step explanation:
Given
y = 
b + 10
Multiply through by 8 to clear the fraction
8y = 5b + 80 ( subtract 80 from both sides )
8y - 80 = 5b ( divide both sides by 5 )
= b
Answer:
Step-by-step explanation:
a) Perimeter of a rectangle = 2 *(L +w)
b) w = L - 2
Answer: B
c) Perimeter = 96 inches
2* (l +w) = 96
2*( L + L - 2 ) = 96 {Combine like terms}
2 * (2L - 2) = 96 {use distributive law}
2*2L - 2*2 = 96
4L - 4 = 96 {Add 4 to both sides}
4L = 96 +4
4L = 100 {divide both sides by 4}
4L/4 = 100/4
L = 25 inches
d) w = L - 2
= 25 - 2
w = 23 inches
