<em><u>Solution:</u></em>
Given that we have to find the sum of 
<em><u>Let us first convert the mixed fractions to improper fractions</u></em>
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator
Therefore,

Now we can add both the fractions

Make the denominators same

Now convert the fraction to mixed number
When we divide 53 by 10 , the remainder is 3
Therefore, write 5 as a whole number and and 3 as numerator and 10 as denominator

Thus the sum of given mixed fraction is 
1) X=159
2) BCD=103
3) DCH=89
im pretty sure
Answer:
Step-by-step explanation:
We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.
So the number of volunteers that donated blood will be 32-n.
We are also told that the rest of the volunteers donated 470 milliliters each.
To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).
Therefore, each of the volunteers donated
millimeters of blood.

Step-by-step explanation:
Given polynomials are:

Both polynomials have to be multiplied. We will use distributive property for the said purpose
So,

Combining alike terms
