Answer:

3, 4, and 5

Step-by-step explanation:

To put it simply, 3 + 4 + 5 = 12 and the numbers are consecutive, next to each other.

The method:

The three consecutive numbers could be called x, x + 1, and x + 2 and we know that x + x + 1 + x + 2 = 12

This can be simplified to 3x + 3 = 12. Next, subtract 3 from both sides to get 3x = 9. Now, divide both sides by 3 to get x = 3.

This means that the first number is 3 and the other numbers are 4 (3 + 1) and 5 (3 + 2).

Hope this helps!

Answer:

  • The numbers are 3, 4 and 5.

Step-by-step explanation:

<u>Let's name the three consecutive number x, x + 1, and x + 2.</u>

  • => x + x + 1 + x + 2 = 12
  • => 3x + 3 = 12
  • => 3x = 9
  • => x = 3

<u>Now, just substitute the value of x into all the numbers to get your answers.</u>

  • => x, x + 1, x + 2
  • => 3, 3 + 1, 3 + 2
  • => 3, 4, 5

Hence, the numbers are 3, 4 and 5.

The difference of two numbers is 15. Five times the smaller is the same as 9 less than twice the larger. Find the numbers
Usimov [2.4K]

Answer:

x= -13

y= -28

Step-by-step explanation:

To find the two numbers, write a system of equations with x as one number and y as another:

x-y=15

5x=2y-9

Use substitution to substitute one equation into another. Then solve for the variable.

x=15+y into 5x=2y-9

becomes

5(15+y) = 2y-9

75+5y = 2y- 9

75+3y= -9

3y = -84

y= -28

To find x, substitute y= -28 into one equation.

x - (-28) = 15

x+28 =15

x = 15-28

x=-13
