Dee saves $20 a week for 10 weeks. during her 5-day vacation, she plans to spend $6.75 each day for snacks. which expression shows how much money she will have left?

$20 a week for 10 weeks is:

20*10 = $200

She spends $6.75 each day for 5 days:

6.75*5 = $33.75.

Lets subtract her spending from her savings to find out how much she has left:

$200-$33.75 = $166.25

5x+2x=49

7x=49

x=7. 35 apples

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
