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

Solve for x: 4(x + 2) = 3(x − 2)<br><br>A) −2<br>B)−4<br>C) −10<br>D) −14
BARSIC [14]

4(x+2)=3(x-2)

Multiply the first bracket by 4

Multiply the second bracket by 3

4x+8=3x-6

Move 3x to the left hand side, whenever moving a number with a letter the sign changes ( positive 3x to negative 3x)

4x-3x+8=3x-3x-6

x+8=-6

Move positive 8 to the right hand side

x+8-8=-6-8

x=-14

Check answer by using substitution method

Use x=-14 into both of the equations

4(-14+2)=3(-14-2)

-56+8=-42-6

-48=-48

Answer is -14- D)
