Answer:

1. $38.5

2. $225

3. $375

4. $225

5. $3.77

Step-by-step explanation:

Each of these problems are asking for a percent. The easy way to get a percent is to do this:

If the percent is in the 1's place (a number like 7%), take the number from the thing your getting the percent from and divide is by 100. So if you had the problem 5% of 50, you're then going to have 0.5

Then, with that number that you have, multiply is by the percent. So with the problem I have shown earlier, you will get 2.5, which is the answers.

If you have a percent that is in the ten's place, then divide by 10and then divide the percentage by 10 THEN multiply.

When you have a percent like 36% or 97% ( a percent with both place values), separate the two place values, do them individually, then add them together.

Find the sum (3.2+4x)+(18.25+6x)=
tatiyna

Answer:    -2.145

Step-by-step explanation:

(3.2+4x)+(18.25+6x)=

Simplifying

(3.2 + 4x) + (18.25 + 6x) = 0

Remove parenthesis around (3.2 + 4x)

3.2 + 4x + (18.25 + 6x) = 0

Remove parenthesis around (18.25 + 6x)

3.2 + 4x + 18.25 + 6x = 0

Reorder the terms:

3.2 + 18.25 + 4x + 6x = 0

Combine like terms: 3.2 + 18.25 = 21.45

21.45 + 4x + 6x = 0

Combine like terms: 4x + 6x = 10x

21.45 + 10x = 0

Solving

21.45 + 10x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-21.45' to each side of the equation.

21.45 + -21.45 + 10x = 0 + -21.45

Combine like terms: 21.45 + -21.45 = 0

0 + 10x = 0 + -21.45

10x = 0 + -21.45

Combine like terms: 0 + -21.45 = -21.45

10x = -21.45

Divide each side by '10'.

x = -2.145

Simplifying

x = -2.145
