Answer:

10 and 7

Step-by-step explanation:

Let the numbers be A and B

The sum of the two numbers is 17.

That’s

A + B = 17

The difference of the numbers is 3

A - B = 3

We now have two equations

1. A + B = 17

2 . A - B = 3

Subtract equation two from equation one.

B - - B = B + B = 2B

2B = 14

Divide both sides by 2

2B/2 = 14/2

B = 7

Now substitute 7 for B into either of the equations to get A.

Using equation 1 we have

A + B = 17

A + 7 = 17

Subtract 7 from both sides

A - 7 = 17 - 7

A = 10

The numbers are 10 and 7

lewis has a bucket with a 5 gallon capacity. lewis puts 12 pints of soapy water in the bucket to wash his car. how many gallons

Tasya [4]

12 pints of soapy water.

8 pints = 1 gallon.

1 pint = 1/8 gallon

12 pints = 12*(1/8)

12 pints = (12/8) gallons

= 3/2 = 1.5 gallons.

Since the bucket is 5 gallon capacity, It can hold:

5 - 1.5

= 3.5 gallons more.

But 1 gallon is = 4 quarts.

3.5 gallons = 3.5 * 4 = 14 quarts more.
