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!

What is the solution to the system of equations x+y=10 and x+2y=4 using the linear combination method?
Elis [28]

Answer:

The solution:

X = 16 and Y = -6

Step-by-step explanation:

The equations to be solved are:

x+y = 10 ------- equation 1

x+2y = 4 ----------- equation 2

we can multiply equation 1 by -1 to make the value of x and y negative.

This will give us

-x- y = - 10 ------- equation 3

x+2y = 4 ----------- equation 2

We will now add equations 3 and 2 together so that x will cancel itself out.

this will give us

y = -10 +4 = -6

hence, we have the value of y as -6.

To get the value of x, we can put this value of y into any of the equations above.  (I will use equation 1)

x - 6 = 10

from this, we have that x = 4

Therefore, we have our answer as

X = 16 and Y = -6
