1) 4x + 3(x-9) = 19

or, 4x + 3x - 27 = 19

or, 7x = 19+27

or, 7x = 46

or, x = 46/7

◆ x = 6.57

2) 2(x-4) + 5x = 3

or, 2x - 8 + 5x = 3

or, 7x = 3+8

or, x = 11/7

◆ x = 1.57

3) 60 = 8y - 3(y-10)

or, 60 = 8y - 3y + 30

or, 60 - 30 = 5y

or, y = 30/5

◆ y = 6

4) 40 + 3c = 3 + 9(c-2)

or, 40 + 3c = 3 + 9c - 18

or, 40 + 3c = 9c - 15

or, 9c - 3c = 40 + 15

or, 6c = 55

◆ c = 9.166

I hope you understand..

Thank you...♥♥

Answer: 300 calories

Step-by-step explanation: let us assume that moving at any speed expends approximately 100 calories per mile. Moving a less-minute mile will burn a few more calories than moving a high-minute mile because of the added effort. Since the minutes for the 3 scenarios are the Same, then we can conclude that he is burning calorie at the same level in which the total equal to 300 calories

An equilateral triangle has a perimeter of 12 x + 18 units. Which expression can be used to show the length of one side of the t
adelina 88 [10]

Answer:

So each side length is 4s+6

Step-by-step explanation:

Since we know the triangle is an equilateral triangle, we know the perimeter of the triangle is given by since all the sides are the same length

P = 3s  where s is the side length

12x+18 = 3s

Divide each side by 3

12x/3 + 18/3 = 3s/3

4s +6 = s

So each side length is 4s+6
