Answer:

-\frac{41}{65}

Step-by-step explanation:

In order to find the answer to this question remember to use KCC (Keep, Change, Change) and find the least common denominator. (LCD)

-\frac{3}{13}-\frac{2}{5}

Use KCC

-\frac{3}{13} +-\frac{2}{5}

Now add

LCD=65

\frac{-3\times5}{13\times5} -\frac{2\times13}{5\times13}

=\frac{-15-26}{65}

=-\frac{41}{65}

Hope this helps.

Yogi is 6 years older than Michelle. The sum of their ages is 26. Write a system of linear equations to represent this informati
postnew [5]

Answer:

10 and 16, x+(x+6)=26

Step-by-step explanation:

Michelle has an age we don't know, so we put her age as x.

Yogi is 6 years older than her, so her age is x+6

Michelle=x

Yogi=x+6

we know both their ages equal 26. so we set it up as

x+(x+6)=26

combining like terms we get

2x+6=26

subtract 6 from both sides

2x=20

divide both sides by 2

x=10

now that we have the value for x, we plug it into their original ages

Michelle is 10, because her age is just x.

Yogi is 16, because her age is x+6

PIT_PIT [208]
1.Simplified each one 
2/5 (both divided by 7) ,  1/2 (divided by 21)
2.Make them into integer
(2/5 )*(2/2)=4/10    ,    (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5
