Answer:
3 3/5 + 1 1/4 = <u>4 17/20</u>
7/8 + 1/12 =<u> 23/24</u>
8/9 - 2/5 = <u>22/45</u>
5 1/4 - 2 2/3 = <u>2 7/12</u>
Step-by-step explanation:
3 3/5 + 1 1/4
First convert into improper fractions
= 18/5 + 5/4
Now find the common denominator
72/20 + 25/20 =
97/20
Now simplify
4 17/20
<u>Next problem:</u>
7/8 + 1/12
find the common denominator
21/24 + 2/24 =
23/24
<u>Next problem:</u>
8/9 - 2/5
find the common denominator
40/45 - 18/45 =
22/45
<u>Next problem:</u>
5 1/4 - 2 2/3
First convert into improper fractions
21/4 - 8/3
find the common denominator
63/12 - 32/12 =
31/12
Now simplify
2 7/12

b.) x (division symbol) 45 + 6
4.)
a.) x decreased by 216
b.) the quotient of 15 and x
Answer:
x=1/5
Step-by-step explanation:
To solve this question we will have to open the bracket first
So let's go back to the given question
-2(5x-1)+7(5x-1)-3(-5x+1)
We can actually equate the equation to zero
Let's solve
-10x+2+35x-7+15x-3=0
Let's collect like terms
-10x+35x+15x=-2+7+3
40x=8
Let's make x the subject of formula by dividing both sides by 40
x=1/5
So the final answer is 1/5
The answer should be "filtration" because distillation is for liquids. Filtration filters out the unwanted products.
