8 + 8( 8 - n ) = 40 + 8n

Ierofanga [76]

n=2

8+8(8-n)=40+8n (distribute 8 through the parenthesis)

8+64-8n=40-8n (add the numbers)

72-8n=40+8n (move the variable to the left side and change its sign)

72-8n+8n=40

-8n+8n=40-72 (connect like terms)

-16n = -32 (divide both sides by -16)

n=2

A 20

B 25

C 10

D 18

8.45% of the battery life of each mobile phone is used in a day by a typical user

Calculating Hours of battery life in a day for each mobile
