Five-sevenths of a number is -35. what is the number?
White raven [17]
So lets write this equation out.  Let x be that number we are trying to find. 

So five-sevenths is a fraction that is written like this 

5/7 

when you see the word "of" that means multiplication 

so we can write the full equation. 

(5/7)x = -35 

now we can solve 

Multiply both sides by 7 

5x = -245

now divide by 5 
and we get 

x = -49

Jan is 2/3 of Karyn's age. Jan's age 8 years ago is 2/5 of Katyn's age 4 yeats from now. Jan is how many younger than Karyn?
Elden [556K]

Answer:

12 years younger.

Step-by-step explanation:

Let Jan's age be J and Karyn's age be K.

J= \frac{2}{3}  K

Jan's age 8 years ago is 2/5 of Karyn's age 4 yeaRs from now.

J-8 = \frac{2}{5} (K+4)

=> (\frac{2}{3} - \frac{2}{5} ) K = \frac{8}{5} + 8

=> 4K = 48 X 3

=> K= 36.

=> J= 24.

So Jan is 12 years younger.
