GIVING BRAINLIEST Katie and Mina both commute to work. Katie's commute on the train takes 10 minutes more than one half as many minutes as Mina's commute by car. It takes Katie 30 minutes to get to work. Write an equation to determine how many minutes it takes Mina to get to work. 30 = one halfx + 10 30 = one halfx − 10 30 = 2x − 10 30 = 2x + 10

Answer 1

Answer:

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

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

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4

Okay, so you are trying to find the total of the basement. Your formula is (L2 + W2). So your length is 35ft. Your W is 28ft. So 35+35= 70ft and 28+28= 56ft. Now 70ft + 56ft is 126ft. 126 is your total
ANSWER: 126 is your answer

Answer: 2.750

Step-by-step explanation:  make 12 7/8 into a decimal then subtract 0.75 to 12.875 than you have 12.125 now you subtract 9. 375 to 12.125 and you have your answer I hope this is right

The answer is 2 6/8

Work-
1. Turn .75 into a fraction which is 3/4.
2. Then change the denominator to be common with the other which would make it 6/8.
3. Then make 12 7/8 into a improper fraction which is 103/8 and subtract the 6/8 to get 97/8.
4. Then change 9 3/8 into an improper fraction which is 75/8.
5. Subtract 75/8 from 97/8 to get 22/8.
6. Lastly, change it to a mixed number which would come out to be 2 6/8.
