x + y = 9

x = 9 - y

2x - y = 0

18 - 2y - y = 0

-3y = -18

y = 6

x = 9 - y

x = 9 - 6

x = 3

BaLLatris [955]

Answer:

5. thirty-four thousand five hundred

6. seven hundred three and two hundred forty-six thousandth

7. seventy-six million eighty thousand

Step-by-step explanation:

These are the answers because:

1) Word form is translating the numbers into words

2) Basically, all you have to do is write the word form the way you pronounce the number

3) Whenever you are round decimals, make sure to have an "and" for the decimal point and "ths" at the end of the value of the number (look at question 6 for reference)

Hope this helps!

Mrs. LoPrimo has 4 sheets of stickers. Mrs. LoPrimo gave 10 stickers away from each sheet. She now has 20 stickers left. How man
valentinak56 [21]

Answer:

4x=20+4(10); x=15

Step-by-step explanation:

20+4(10)=4x

This is where x is the number of stickers per sheet.

This is the equation because she has 20 stickers.

To find the original number of stickers, we have to add back the amount given.

She has 4 sheets and gave 10 stickers from each sheet. This means she gave away 4*10 stickers.

Now, we can solve the equation:

20+40=4x

60=4x

x=15
