Question

Write and solve an equation to solve each problem. the sum of 3 consecutive numbers integers is 90. find the integers.

Answer 1

Answer:

29, 30, 31

Step-by-step explanation:

since they are three consecutive numbers, label the first number x, the second x+1, and the third x+2. set up an equation by adding them and setting them equal to 90 as shown below:

x+(x+1)+(x+2)=90

then, solve the equation:

3x+3=90

3x=87

x=29

x+1=30

x+2=31

The integers are 29, 30, and 31.
