There are 128 ounces in 1 gallon

1,5gallons= 192 ounces

Scott = 3 oz per lid

192 divided by 3 = 64 lids of detergent

Nikki = 4oz per lid

192 divided by 4 = 48 1/2 lids

64 - 48.5 = 15.5 lids more

Step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
