Answers

• We have the enunciation, now we can solve.
♦ We note :
- t, the price of the table;
-c, the price of a chair:

3t+2c=1850   } 
t=c+75          }  =>

=> 3(c+75) +2c=1850
3c+225+2c=1850
5c=1850-225
5c=1625
c=1625:5
c=341=> t=341+75 = 476 .

0 is 0%.

1/2 is 50%.

1 is 100%

30 is 30 away from 0, 20 away from 50, and 70 away from 100.

Janet is 5 years older than her sister.the sum of their ages is 51.how old is her sister

Answers

Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
   = 23
So the age of Janet = x + 5
                                = 23 + 5
                                 = 28 years
So the age of Janet's sister is 23 and Janet's age is 28
To find how old old her sister is you just do 51 -5 which will give you 46.
