Mason used a 30% coupon to buy a new computer. after the discount, the cost of the computer was $728. determine the original price of the computer. show your work.

1040

Step-by-step explanation:

"1x-0.30x=728"

move all terms to the left:

1x-0.30x-(728)=0

add all the numbers together, and all the variables:

0.7x-728=0

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

0.7x=728

x=728/0.7

x=1040

Step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
