Q. A set of 3 consecutive integers adds up to 15. Which integers are they?_, _, _
Define First Integer: Let x be the first integer.Consecutive integers increase by 1 each time.Consecutive integers: x, x+1, x+2
Set Up Equation: Set up the equation that represents the sum of 3 consecutive integers equal to 15. Add three consecutive integers and equate the sum to 15. Equation: x+(x+1)+(x+2)=15
Simplify Equation: Simplify the left side of the equation x+(x+1)+(x+2)=15.x+(x+1)+(x+2)=15(x+x+x)+(1+2)=153x+3=15
Isolate Variable Term: Isolate the variable term in the equation 3x+3=15. 3x+3=15 3x+3−3=15−3 3x=12
Solve for x: Solve for x.3x=1233x=312x=4
Determine Consecutive Integers: Determine the 3 consecutive integers that add up to 15.Three consecutive integers:x, x+1, x+24, 4+1, 4+24, 5, 150
