Answer from: mrfloyd1250

percentage change from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

= 44 %

Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

= 230.55%

percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

= 13.44%

percentage change from 1990 to 2000 = (- 0.09 ÷ 1.35) × 100

= -6.667%

Step-by-step explanation:

Item : 1960 1970 1980 1990 2000

gallon: $0.25 $0.36 $1.19 $1.35 $1.26

change : 0.36 - 0.25 = 0.11

percentage change from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

= 44 %

Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

= 230.55%

percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

3; 9 is 8 to -4

step-by-step explanation:

Answer from: Quest

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
