What is 4 - 7f = f - 12

1 answer:

6 0

4 - 7f = f - 12

Subtract f from both sides.

4 - 7f - f = -12

Subtract 4 from both sides.

-7f - f = -12 - 4

Simplify.

-8f = -16

Divide both sides by -8.

f = 2

To show your work, simply plug in the value of f into the original equation.

When f = 2, :

4 - 7f = f - 12

4 - 7(2) = (2) - 12

Simplify.

4 - 14 = 2 - 12

Simplify.

-12 = -12

So, f = 2

Zane bought a pair of jeans that originally cost $56. He used a coupon for 25% off and paid 8% in sales tax. How much did he pay

sattari [20]

Answer:

$38.64

Step-by-step explanation:

so the equation needed to solve is $56*0.25 and that number is 14. Since it is a coupon you subtract 14 from 56 and end up with 42. Now multiply 0.08*42 and you got your sales tax, $3.36. now subtract that from 42 and you have your answer! Don't forget the dollar sign!

hope this helped! : )
