Luisa has a business selling hair clips at the mall. currently he business has a balance of -& 15. which amount of sales would give luisas business a positive balance? $25,$19,$20,$14,$10 or $10

Step-by-step explanation:

We know that Luisa has a balance of -15, that means she owes $15.

So, if Luisa wants to have a positive balance, she need to sale more than $15.

That means $25, $19 and $20 are the amount of sales that would give her a positive balance because

25 - 15 = 10

19 - 15 = 4

20 - 15 = 5

All of them give a positive balance.

Therefore, the right answers are $25, $19 and $20.

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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
