Seven times the first (smaller) of two consecutive odd integers is equal to five times the second (larger) integer. Find each in
lbvjy [14]
<h2>Answer:</h2>
  • The smaller consecutive odd integer is: 5
  • and the larger consecutive odd integer is: 7
<h2>Step-by-step explanation:</h2>

Let the smaller odd integer be: a

then the larger odd integer which is consecutive to a will be: a+2

It is given that:

Seven times the first (smaller) of two consecutive odd integers is equal to five times the second (larger) integer.

This means that:

7 times of a is equal to 5 times of (a+2)

i.e.

7a=5(a+2)\\\\i.e.\\\\7a=5\times a+5\times 2

( Since, by using the distributive property of multiplication)

i.e.

7a=5a+10\\\\i.e.\\\\7a-5a=10\\\\i.e.\\\\2a=10\\\\i.e.\\\\a=5

Hence, the smaller number is:  5

and the larger number is: 7

( Since a+2=5+2=7 )

MARK AS BRAINLIEST PLZZZ

Answer:

Son + Daughter 60%

Son -  23,625

Daughter - 16,875

Wife % - 40%

Total - 67,500

Step-by-step explanation:

1. We do 35 + 25 to get 60

2. 27000 / 40 to get 1% = 625

Then, 625 x 35 = 23,625

3. 625 x 25 = 16,875

4. 100 -  60 ( kids )  = 40%

5. 40500 ( kids ) + 27000 = 67, 500
