Question

2. The sum of three consecutive odd numbers is 75. Find the numbers.
15. Divide 25 into two parts such that 7 times the first part added to 5 times
139.​

Answer 1

Answer:

LET THE NUMBERS BE x,x+1,x+2

Then

x + x+1 + x+2=75

3x=72

x=24

x+1=25

x+2=26

24+25+26=75

Answer 2

Answer:

hope it was helpful.

Step-by-step explanation:

let numbers be = x,x+1,x+2 ( they are consecutive)

so, x+x+1+x+2= 75

3x+3=75

3x= 75-3

x= 72/3

x= 24

then other numbers = 24+1 = 25 ,

24+2 = 26

(2) let first part be x

and second = 25-x

we know,

=  7x+5(25-x) = 139

= 7x + 125-5x = 139

= 7x-5x= 139-125

=2x= 14

=x=14/2

= x = 7

they other number = 25 - 7
