Final Answer: c = 10

Steps/Reasons/Explanation:

Question: Solve for the given variable: 75c - 300 = 25c + 200.

<u>Step 1</u>: Add 300 to both sides.

75c = 25c + 200 + 300

<u>Step 2</u>: Simplify 25c + 200 + 300 to 25c + 500.

75c = 25c + 500

<u>Step 3</u>: Subtract 25c from both sides.

75c - 25c = 500

<u>Step 4</u>: Simplify 75c - 25c to 50c.

50c = 500

<u>Step 5</u>: Divide both sides by 50.

c = \frac{500}{50}

<u>Step 6</u>: Simplify \frac{500}{50} to 10.

c = 10

~I hope I helped you! :)~

What is the value of n in the equation 1/2 (n-4) - 3 = 3 - (n+3) ?
photoshop1234 [79]

Answer:

10/3 or 3 1/3

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

0.5(n-4)-3=3-(n+3)

First, you would do the distributive property:

0.5n-2-3=3-n-3

Then you would simplify and then solve.

0.5n-5=-n

-5=-1.5n

n=5/1.5

n=10/3 or 3 1/3

Two less than five times a number is 28. what is the number
marissa [1.9K]
The number is 6 because five times 6 is 30, and 30 minus 2 is 28. You could also solve this backwards in the future and take 28 plus 2 and then divide that number by 5 (opposite of subtracting 2 is adding two, opposite of multiplying by five is dividing by 5). 

5x-2=28    (writing it this way might also help, because now you just have to solve for x)

(219,379.01 - x) / x = .3321
Ivahew [28]

Answer:x = 164686.592598

Step-by-step explanation:

219379.01−x/x = 0.3321

−x+219379.01/x = 0.3321

Step 1: Multiply both sides by x.

−x+219379.01≈0.3321x

−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)

−1.3321x + 219379.01 = 0

−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)

−1.3321x = −219379.01

−1.3321x/−1.3321 = −219379.01/−1.3321

(Divide both sides by -1.3321)

x = 164686.592598
