Question

find the three multiples of 5 whose sum is 230​

Answer 1

Answer:

answer is 70,75 and 85

Step-by-step explanation:

Any multiple of 5 can be written as 5x.

The next multiple will be when x increases by 1.

The sum of 3 multiples of 5is 230.

so 5x+5(x+1)+5(x+3)=230

=5x+5x+5+5x+15=230

=15x+20=230

=15x=230-20 = 210

=x=210÷15=14

5x=14 ×5=70

5(x+1)= 5x+5 =75

5(x+3)=5x+15=85

and the sum of 70,75 &85 is230.

so the multiples are 70 ,75 and 85
