Answer:

2.33 hours

Step-by-step explanation:

Given

Veteran Tutor

Charges = \$15 --- first session

Hourly\ Rate = \$60

College Graduate

Charges = \$45 --- first session

Hourly\ Rate = \$50

Required

Determine the number of hours they earn the same amount

Represent the hours with x

First, we need to calculate the total charges for the veteran tutor for x hours;

Total = 15 + 60x

Next, we need to calculate the total charges for the college graduate tutor for x hours;

Total = 45x + 50

For them to earn the same amount, we have:

15 + 60x = 45x + 50

Solving for x

60x - 45x = 50 - 15

15x = 35

Divide through by 15

x = \frac{35}{15}

x = 2.33\ hours

Rewrite in simplest terms: -7(5v-10)-7v
Over [174]

Answer: -42v + 70

Step-by-step explanation: You’d multiply -7 with the figures in the brackets, then you’d group like terms then subtract -7v from -35v.

1. -35v + 70 - 7v

Negative multiplied by negative is a positive

2. -35v - 7v + 70

Group like terms

3. -42v +70

Subtract

A phone plan charges $15.95 per month and $0.10 for every minute, m, that the phone is used. Mr. Kordemsky wants his phone bill
aleksandrvk [35]

Answer:

The inequality that could be used to model this situation is 15.95+0.10m<40. Also, the number of minutes has to be less than 240.5 for Mr. Kordemsky's phone bill for the month to be less than $40.

Step-by-step explanation:

From the information provided, the inequality would indicate that the phone bill for the month that is equal to the result of the fixed fee plus the price per minute for the number of minutes has to be less than $40, which can be expressed as:

15.95+0.10m<40

Now, you can solve for m:

15.95+0.10m<40

0.10m<40-15.95

0.10m<24.05

m<24.05/0.10

m<240.5

According to this, the answer is that the inequality that could be used to model this situation is 15.95+0.10m<40. Also, the number of minutes has to be less than 240.5 for Mr. Kordemsky's phone bill for the month to be less than $40.
