We must find the common denominator.

5 goes into 15, but to get 5 to 15, we must multiply by 3. When doing this, we have to multiply the numerator by the same thing.

1 x 3 = 3
5 x 3 = 15

3/15 is the new fraction. Because we’re subtracting, it would be easier to convert the mixed number (7 3/15) into an improper fraction. 7 x 15 = 105 + 3 = 108. 108/15 is the improper fraction. 3 x 15 = 45 + 11 = 46. 46/11 is the other improper fraction.

108 - 46 = 62.

62/15 = 4 2/15.

4 2/15 is the final answer.

Answer:

2(1/5)

Step-by-step explanation:

7(1/5) - 3(11/5)

= {(35 + 1)/5} - {(14+11)/5}

= (36/5) - (25/5)

Take the LCM of the denominator 5 and 5 is 5 as common.

= (36*1 - 25*1)/5

= (36 - 25)/5

= 11/5

= 2(1/5) → [Mixed fraction] Ans.

Please let me know if you have any other questions.

mel-nik [20]

Answer:each session of body sculpting workouts burns 51 calories.

Each session of Yoga workouts burns 83 calories.

Step-by-step explanation:

Let x represent the number of calories that she burnt doing one body sculpting workout session.

Let x represent the number of calories that she burnt doing one Yoga session.

Last week, she burned a total of 517 calories by doing 2 body sculpting workouts and 5 yoga sessions. This means that

2x + 5y = 517 - - - - - - - - - -1

This week, she has completed 2 body sculpting workouts and 1 yoga session and burned a total of 185 calories. This means that

2x + y = 185 - - - - - - - - - - - - 2

Subtracting equation 2 from equation 1, it becomes

4y = 332

y = 332/4 = 83 calories

Substituting y = 83 into equation 2, it becomes

2x + 83 = 185

2x = 185 - 83 = 102

x = 102/2 = 51 calories

If g(x) = 2(x − 4), find the value of x if g(x) = 20. 32 12
nlexa [21]

Answer:

The value of x is 14

Step-by-step explanation:

we have

g(x)=2(x-4) ------> equation A

In this problem we have

g(x)=20

Substitute the value of g(x) in the equation A and solve for x

20=2(x-4)

Divide by 2 both sides

20/2=2(x-4)/2

10=(x-4)

Adds 4 both sides

10+4=(x-4)+4

x=14
