the sum of three numbers is 79. The second number is 5 times the first, while the third is 16 more than the first. Find the numb
swat32
Let the 1st number be x; 2nd number be y; 3rd number be z.

x + y + z = 79

x = number we are looking for.
y = x * 5 ==> 5 times the first
z = x + 16 ==> 16 more than the first

Therefor,

x + (x * 5) + (x+16) = 79

1st step, multiply the 2nd number: x * 5 = 5x

x + 5x + x + 16 = 79

Add all like numbers:

7x + 16 = 79

To get x, transfer 16 to the other side and change its sign from positive to negative.

7x = 79 - 16
7x = 63

To get x, divide both sides by 7

7x/7 = 63/7
x = 9

To check. Substitute x by 9.

x + (x * 5) + (x+16) = 79

9 + (9 * 5) + (9 + 16) = 79
9 + 45 + 25 = 79
79 = 79 equal. value of x is correct.

How do u turn 4/10 into a fraction and percent
Delvig [45]
4/10 can be simplified to 2/5. 1/5 is equal to 20% (you probably want to memorize that) so all you have to do is multiply 20% by 2 (because of the numerator) and get 40%
So therefore 4/10 = 2/5 or 40%
P.S if you have anything over ten that needs to be a percent just multiply 10% by the numerator.

Find the value of x.
andrew11 [14]

Answer:

50

Step-by-step explanation:

The upper left hand arc is also 130

The lower right hand arc is also x

A circle all the way around from some starting point is 360 degrees.

x + x + 130 + 130 = 360            Equation. Combine like terms.

2x + 260 = 360                         Subtract 260 from both sides

2x = 360 - 260                    

2x = 100                                    Divide by 2

x = 100/2

x = 50
