PLEASE MARK BRAINLIEST!

Answer for 5x+3x=420

Step 1: Simplify both sides of the equation.

5x+3x=420

(5x+3x)=420(Combine Like Terms)

8x=420

8x=420

Step 2: Divide both sides by 8.

\frac{8x}{8} = \frac{420}{8}

x = \frac{105}{2}

Answer for 12x+9=1080

Step 1: Subtract 9 from both sides.

12x+9−9=1080−9

12x=1071

Step 2: Divide both sides by 12.

\frac{12x}{12} = \frac{1071}{12}

x = \frac{357}{4}

Select the number line that shows the decimal for the following fraction.<br><br> sixth tenths
Komok [63]

Answer:

C

Step-by-step explanation:

to figure this out, lets understand how decimals work

a decimal number in the tens place before the decimal

  ↓ here

0.00

that number will be the same number as the numerator or top number of a fraction in tenths

↓ here

0/10

so say it was 4/10 we needed to find, we would look on the number line for 0.40 like in answer choice B (NOT THE CORRECT ANSWER FOR THIS PROBLEM)

hope this helps you out on your work :)
