If solving for y

remember, you can do anything to an equation as long as you do it to both sides
y-12=-22
add 12 to both sides
y+12-12=12-22
y+0=-10
y=-10

A number, one-fourth of that number, and one-third of that number are added. The result is 38. What is the original number?​
Hatshy [7]

Answer:

24

Step-by-step explanation:

Let 12x represent the original number.

One fourth of that number can be represented by 3x, and one third of the number can be represented by 4x.

Create an equation that sets this equal to 38, and solve for x:

12x + 3x + 4x = 38

19x = 38

x = 2

The original number is represented by 12x, so plug in 2 as x:

12(2)

= 24

So, the original number is 24.

A triangle has a perimeter of 112 cm. Each of the two longer sides of the triangle is three times as long as the shortest side.
Ugo [173]

Answer:

Two sides have a measure of 48 cm and the shortest side is 16 cm.

Step-by-step explanation:

this is an isosceles triangle

let x = length of shortest side

let 3x = length of other two sides

find x:

3x + 3x + x = 112

7x = 112

x = 16

3x = 48
