Select the correct answer from each drop-down menu. a self-service car wash charges $4 for the initial 5 minutes plus an additional $0.75 for each minute after that. nick only has $10 to spend on washing his car. let m represent the number of minutes nick spends washing his car. create the inequality that symbolizes this situation. m + ? a car enthusiast magazine recommends spending at least 15 minutes to properly wash a car. does nick have enough money to follow this recommendation?

Nick needs $11.50 to wash his car for at least 15 minutes. But, he has only $10. So, he does not have enough money.

Explanation:

Given information : A self-service car wash charges $4 for the initial 5 minutes plus an additional $0.75 for each minute after that.

Let the cost for car wash for M minutes be = x

Equation forms; ; .....(1)

when M= 5, x=4 (initial 5 minute cost)

Now, we also know that one should spend at least 15 minutes to properly wash a car. So, inequality for number of minutes become

Now plugging in equation (1) we get,

This shows that Nick needs $11.50 to wash his car for at least 15 minutes. But, he has only $10. So, he does not have enough money.

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
