Question

Four times the difference between 44 and Sarah's age (a) is 64. Assume Sarah is younger than 44.
Represent the above statement by an equation.

Answer 1

Start out by writing the problem mathematically. Let Sarah's age = x
Therefore, four times the difference between 44 and x is 64 can be written
4x-44 = 64


Now solve for x.
Add 44 to both sides.
4x = 108
Divide each side by 4.
x = 27. Therefore Sarah is 27 years old.

Answer 12

John has read the first 114 pages of a novel. He has read 3 pages less than one-third of the novel.
Write an equation to describe the total number of pages p in the novel, and find the value of p.
hellppp

Answer 13

114 + 3 = p/3
117 = p/3 both sides times 3 getting
p = 351

Answer 14

Sara's age: 4(44 - a) = 64 Divide both sides by 4 getting 44-a = 16.
Subtract 44 from both sides getting: -a = 16 - 44 or -a = -28
Multiply both sides by -1 getting a = 28.
