Answer:

X=8

Step-by-step explanation:

-2(x-4)=8

Divide both sides by -2−2.

x-4=-8\-2

Two negatives make a positive.

x-4=8/2

Simplify  8/2 to 4

x-4=4

Add 4 to both sides.

x=4+4

Simplify  4+4 to  8.

x=8

Answer:

x=8

Step-by-step explanation:

-2(x-4)=8

distribute

-2x+8=-8

add 2x to both sides

-2x+2x+8=-8+2x

8=-8+2x

devide both sides by 2

4=-4+x

add 4 to both sides

8=x

A wireless company offers two cell phone plans. For the month of September, Plan A charges $35 plus $0.25 per minute for calls.
valentina_108 [34]

Answer:

60 minutes

Step-by-step explanation:

Let the number of minutes be represented as x

For Plan A

Plan A charges $35 plus $0.25 per minute for calls.

$35 + $0.25 × x

35 + 0.25x

For Plan B

Plan B charges $20 plus $0.50 per minute for calls.

$20 + $0.50 × x

20 + 0.50x

For what number of minutes do both plans cost the same amount?

This is calculated by equating Plan A to Plan B

Plan A = Plan B

35 + 0.25x = 20 + 0.50x

Collect like terms

35 - 20 = 0.50x - 0.25x

15 = 0.25x

x = 15/0.25

x = 60 minutes.

Hence, the number of minutes that both plans cost the same amount is 60 minutes
