Answer:
x= -12
Step-by-step explanation:
move variable to left and change its sign
= 4x - 20 = -68
move constant to the right and change its sign
= 4x = -68 + 20
calucate the sum
= 4x = -48
divide both sides of the equation by 4
x= -12
Answer:
= X + 8.2
Step-by-step explanation:
Answer:
length = 20 ft, width = 11 ft
Step-by-step explanation:
let w be width, then length = w + 9
The opposite sides of a rectangle are equal , then
2w + 2(w + 9) = 62
2w + 2w + 18 = 62
4w + 18 = 62 ( subtract 18 from both sides )
4w = 44 ( divide both sides by 4 )
w = 11
and w + 9 = 11 + 9 = 20
then width = 11 ft and length = 20 ft
Answer:
Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108. Thus, 3x+6 = 108.
