Simplifying -2x + -4y = 9 Solving -2x + -4y = 9 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4y' to each side of the equation. -2x + -4y + 4y = 9 + 4y Combine like terms: -4y + 4y = 0 -2x + 0 = 9 + 4y -2x = 9 + 4y Divide each side by '-2'. x = -4.5 + -2y Simplifying x = -4.5 + -2y13/18

Choose the word that makes the sentence true. The first digit in the quotient 1,875 ÷9

Hi, I'm Jenny from ExperimentsDIYS and I'm here to help you with your math! :)

I am assuming that you need help with question #1 so we will proceed with that one.

Lets first divide 1,875 ÷ 9.

Using a calculator, this is equal to 208.333333333

We can simplify this number by rounding up.

208.33 would be your answer rounded.

The first digit in this quotient ( Which is the answer to a division problem) is using place value.

The decimal place value chart is attached.

The first digit will be in the hundreds place because it is on the left side of the decimal point.

We are ecstatic to help and if there are any more problems or if we got any answers wrong please tell us! Thank you <3
