The sum of three numbers is 50. One number is five more than a second number. It is also twice the third. Find the numbers.

1 answer:

8 0

Let
One Number = x
Second Number =x-10
Third Number=x/2

Sum of three numbers is 50
x+x-10+x/2=50
2x-10+x/2=50
Multiply by 2 both sides
2*(2x-10+x/2)=50*2

4x-20+x=100
5x=100+20
5x=120
x=120/5
x=24

One number = x=24
Second number =x-10=24-10=14
Third number= x/2=24/2= 12

The equation the quantity 2x minus 20 divided by 3 = 2x models temperature change, where x represents the difference in degrees

irina [24]

The solution to the equation is x = -5

<h3>How to determine the value of x?</h3>

The equation is given as:

the quantity 2x minus 20 divided by 3 = 2x

Rewrite properly as

(2x - 20)/3 = 2x

Multiply through by 3

2x - 20 = 6x

Collect like terms

6x - 2x = -20

This gives

4x = -20

Divide by 4

x = -5

Hence, the solution to the equation is x = -5
