Ok. First you isolate the variable. So Ill take 12 which is posotive, and subtract 12 from the 15 and the 12. Now all were left with is -x=3. We multiply each side by -1 to give us x=-3. Hope this helps!

One number is 23 more than another. If the sum of the two numbers is 163, find the two numbers.
kipiarov [429]

ANSWER

93 and 70

EXPLANATION

We have that one number is 23 more than another.

Let the first number be x.

Let the second number be y.

This means that:

x = 23 + y ____(1)

The sum of the two numbers is 163. This means that:

x + y = 163 ____(2)

Put (1) in (2):

23 + y + y = 163

23 + 2y = 163

2y = 163 - 23

2y = 140

y = 140 / 2

y = 70

From (1):

x = 23 + 70

x = 93

The two numbers are 93 and 70.

Zoe Had A Board 5 And 1/4 Feet Long. She Cut Off A Piece. Now The Board Is 3 And 5/6 Feet Long. How Long Was The Piece She Cut O
Sergio039 [100]
Well first you need to find the LCM (least common multiple) of 4 and 6 (the denominators) so that you can subtract them from each other.

4: 4,8,12,16,20
6: 6, 12, 18, 24
The LCM is 12.

Now we can subtract the two mixed numbers by turning them into improper fractions.

5 3/12 -> 27/12
3 10/12 -> 42/12

42-27=15

The fraction is 15/12, which simplifies into 1 1/4.

She cut off 1 1/4 feet of the board.
