You are going to mix a gallon bucket of window cleaner. the instructions direct you to mix 1 part cleaner to 3 parts water. how much cleaning solution will you need to use? *
1 ½ quarts 1 pint 2 quarts 1 quart

Option D. 1 quart

Step-by-step explanation:

In a solution of 1 gallon we have to calculate the amount of cleaning solution will be needed.

Since mixture prepared will be in the ratio of 1 : 3 (cleaning solution : water)

So total amount of cleaning solution in 1 gallon = gallon

As we know 1 gallon = 4 quarts

so gallons = ()(4) = 1 quart

Therefore, 1 quart of the cleaning solution will be added.

i pretty sure it is

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
