Answer:

2x + 10 =20

x^2 - 3 = 22

5x + 5 = 30

Step-by-step explanation:

Keeping in mind that x is 5, I just performed the operations to know what should be on the right side of the equal sign.

for eg: 2(5) + 10 = 20

(5)^2 - 3 = 22

5(5) + 5 = 30

I found 50, making a rule of three where
 40__10
  x___25

x=10
 40+10= 50
( I hope I'm right, but from what I understand this would be the resolution)

0.1 is 10% of what number?
stiv31 [10]
Let's assign a variable that is the number when multiplied by 10% it is equal to 0.1.

Well let that be x.

Now we want to convert the 10% into a decimal. To convert a percent into a decimal, simply move the % sign two places to the left and make it into a decimal point.

When we say "of" in mathematics what we really mean is to multiply.

0.10 * x = 0.1

That is the equation we need to find the value of x for.

Divide both sides by 0.10

0.10 * x = 0.1

The 0.10 on the left side cancels out.

x = 1

So, the answer to this question is if we multiply 10% by 1 we will get 0.1.

*<br> What is the value of x?<br> (x + 35)<br> (3x + 1)<br> x =<br> plzzz help due in 40 mins!
Brilliant_brown [7]

Answer: (x=+17)

Step-by-step explanation:

x+35=3x+1

We move all terms to the left:

x+35-(3x+1)=0

We get rid of parentheses

x-3x-1+35=0

We add all the numbers together, and all the variables

-2x+34=0

We move all terms containing x to the left, all other terms to the right

-2x=-34

x=-34/-2

x=+17
