18) Let x be the number of coins in the pouch:

3x + 3 = 9; subtract 3 from each side:

3x + - 3 = 9 -3

3x = 6 . Now divide both side by 3:

x = 2 (in each pouch we have 2 coins)

19) SAME logic:

4x + 1 = 2x + 7; subtract 1 from each side:

4x + 1 - 1 = 2x + 7 - 1
4x = 2x + 6; now subtract 2x from each side:

4x - 2x = 2x + 6 - 2x

2x = 6   and x = 3 (each pouch contains 3 coins)

Mazyrski [523]

Answer:

(a-f)/6 = r

Step-by-step explanation:

The total Bonnie must pay is the weekend fee plus the hourly rate times the hours worked

Cost = weekend fee * hourly rate* hours

hours = 6

weekend fee =f

hourly rate = r

Cost = a dollars

Substituting in what we know

a = f+ 6r

We want to solve for r

Subtract f from each side

a-f =f-f +6r

a-f = 6r

Divide each side by 6

(a-f)/6 = 6r/6

(a-f)/6 = r
