Solve for x and y x+y=32 x−y=8

Answers

Answer 1

Answer:

Answer:

x = 20 y= 12

Step-by-step explanation:

x+y=32

x−y=8

Add the two equations together to eliminate y

x+y=32

x−y=8

----------------

2x = 40

Divide each side by 2

2x/2 = 40/2

x = 20

We know x so we can find y

x+y = 32

20+y = 32

20+y-20 = 32-20

y= 12

How to work out math problem %of 50 shirts is 35 shirts

Answers

50 shirts is equal to 100% of the shirts right? So, to find what percentage 35 shirts is, you can divide 35 by 50 to get the decimal value of the percentage. This gives you 0.7, which is the same as 70%.

35 shirts are 70% of 50 shirts.

"of' is multiplication.
"is" is equal.
So x% of 50 is 35 could be written as
x% $*$ 50 = 35

The first step is to divide by 50 on both sides.
x% times 50 divided by 50 is x%.
35 divided by 50 is .7

So x% = .7.

The next step is to get rid of the percent sign to find the value of x (our answer). To do this, we multiply by 100 on both sides.
x% times 100 is x.
.7 times 100 is 70%.

So x = 70%.

The answer:
70% of 50 shirts is 35 shirts.

Spencer took $21 with him to the mall. At the music store he spent 2/3 of his money on a DVD. Then spent 1/4 on a drink. How much money does spencer have left?

Answers

After the music store he had $14 left, because 21:3=7 and 7x2 equals 14.

After the drink, he has $3.5 left, because 14:4=3.5 and 3.5x1=3.5.

Conclusion: that is one expensive drink. (Answer is 3 dollars and 50 cents. Hope this helped:)

Ok to solve this problem we need to first find how much he spend in the mall. We put the 2 fractions into like denominators which is 12. If we convert it we get a total of 11/12. So he spent 11/12 of his money. One way you can solve is by figuring out how much 11/12 is and subtract that by 21. Then you will get 19.25
21 minus 19.25 is 1.75 dollars. Another way is to just find out how much is 1/12 of 21. Then you will get $1.75. So Spencer has 1.75 dollars left. I hope this helps!

What is the area of a rectangle with the height of 25mm, and the length of 12mm? After you get the product, turn it into feet.

Answers

Area = (length) x (width) = (25mm x 12mm) = 300 square millimeters

You can't convert 'square millimeters' to feet. One is a unit of area,
but the other is a unit of length.

You can convert square millimeters to square feet, though.

(300 mm²) x (1 ft / 304.8 mm)² = 0.00323 square foot (rounded)

300 feet is the answer
