Answer: each eraser cost 5 dollors                

Step-by-step explanation: Simplifying

25 = 5 + 4e

Solving

25 = 5 + 4e

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.

Add '-4e' to each side of the equation.

25 + -4e = 5 + 4e + -4e

Combine like terms: 4e + -4e = 0

25 + -4e = 5 + 0

25 + -4e = 5

Add '-25' to each side of the equation.

25 + -25 + -4e = 5 + -25

Combine like terms: 25 + -25 = 0

0 + -4e = 5 + -25

-4e = 5 + -25

Combine like terms: 5 + -25 = -20

-4e = -20

Divide each side by '-4'.

e = 5

Simplifying

e = 5

fgiga [73]
$20.00 ≥ 7.50+1.25x
subtract 7.50 from both sides
20-7.50=12.50
12.50=1.25x
12.50/1.25=10
x= 10 rides

Any help would be appreciated! :)

Answer:

-7, then -13, then -19

Step-by-step explanation:

Plug in x values to get y.

y = -2(0) - 7

y = 0 - 7

y = -7

y = -2(3) - 7

y = -6 - 7

y = -13

y = -2(6) - 7

y = -12 - 7

y = -19

Hope this helps. :0)
