Pablo is thinking of a number. When he doubles it and then adds 13 the resulting answer is 5.Construct an equation and solve it to determine the number Pablo is thinking of.

Answers

Answer:

x×2+13=5

Step-by-step explanation:

We use x as the unknown number, and we just put what's in the word problem! The answer is in the question.

Equation Set-Up

x×2+13=5

Remember order of operations! (PEMDAS)

Then you solve the equation.

Because of PEMDAS, we know that multiplication is the first thing we have to do.

x×2=2x

So now, our equation looks like this.

2x+13=5

We subtract 13 from the +13 to cancel it out, but that means that we also have to subtract 13 from the 5 on the other side. We are now left with this.

2x=-8

Then, we divide -8 by 2, which gives us...

x=-4

Pablo's number is -4.

I hope I helped! Have a great day.

Answer:

18/24 or 75%

Step-by-step explanation:

Okay so you already know that he got 16/24 which means that there were 8 questions that were wrong because 24-16= 8

So he has 16 points that we know of and 8 questions that he got wrong.

If he lost 1/4 of a point when he got it incorrect 1/4= 0.25

0.25 x 8 = 2points

So he got to points

16+ 2= 18 so now it is 18/24

If you have to show Out for 100% it would be 75%

Hope it helped!

Step-by-step explanation:

first, simplify 30/2c. which is 15/2c. then cross multiply. 15 x 12 = c x 20.

you get 180 = c x 20. swap sides, c x 20 = 180. divide both sides by 20, then simplify to get 9.
