assuming you want us to solve for x

remember that you can do anything to an equation as long as you do it to both sides


18x+20+x=10x-3

combine like terms

19x+20=10x-3

minus 10x from both sides

19x-10x+20=10x-10x-3

9x+20=0-3

9x+20=-3

minus 20 from both sides

9x+20-20=-3-20

9x+0=-23

9x=-23

divide both sides by 9

\frac{9x}{9}=\frac{-23}{9}

x(\frac{9}{9})=\frac{-23}{9}

x(1)=\frac{-23}{9}

x=\frac{-23}{9}

18x + 20 + x = 10x -3

Combine like terms

19x + 20 = 10x -3

Subtract 20 to both sides because whatever you do on one side you have to do it on the other side:

19x = 10x -23

Subtract 10x

9x = -23

Divide 9 to isolate x:

x = -23/9

Simplify to get a mixed number:

x = -2 5/9

A spinner is divided into 10 congruent sections, numbered 1 through 10. If Cleo spins the spinner once, what is the probability
mario62 [17]

Answer:

20% or 1/5 or 0.2

Step-by-step explanation:

1. There are 10 sections, which means <em>each section has a a chance of 10% to be landed on</em>.

2. There are <em>two multiples of four under 10: 4 and 8</em>.

That means there is a <em>2 * 10%</em> = 20% chance that the spinner will land on a multiple of 4.

Help please ASAP!!!!
Semenov [28]

The answer would be 65.9%. Add both paper numbers together (26.5+51.3) which is to 77.8.. to find paper not recycled just put 51.3/77.8 which would be 0.659 as a decimal.. move the decimal over to the right twice and that'd be your percentage.
