The answer would be: X=26
Answer:
C. 2.5 or 5/2
Step-by-step explanation:
The topics you should learn are equating denominators and fractions. This is summing up simple fractions.
So we have to make denominators' numbers the same in order to sum up them all (we can sum fractions if the denominators are the same) , and we did it by cross product (that thing on the picture)
Equating by lcm (least common multiple) is the easiest way, because you might see bigger numbers on other questions, and cross product will bring much bigger numbers, so this technic might confuse you.
By the way lcm of 4 and 5 is already 20

Answer:
DEF or EAD or DEA
Step-by-step explanation:

its like multiplication 1 times 1 times 2 equals two whether the questions is asked 1 times 2 times 1 or 2 times 1 times one
hope this helps!
