The right answer to 1b is 1 5/8 and the right answer to number 1e is 1 3/7. The way I solved this was by starting out adding two fractions at a time...
1b). 5/8 + 5/8 + 3/8
5/8 + 5/8 = 10/8 or 1 1/4
10/8 + 3/8 = 13/8 or 1 5/8.
1e). 5/7 + 1/7 + 4/7
5/7 + 1/7 = 6/7
6/7 + 4/7 = 10/7 or 1 3/7

Here we want to find the proportional relationship between the number of hours that Abdul charges the suit and the number of hours that he can fly.
We will get the proportional relationship:
y = 2*x
where y is the number of hours that Abdul can fly and x is the number of hours that he charges the suit.
<h3>Proportional relationships:</h3>
A proportional relationship is a linear relationship of the form:
y = k*x
Where k is the constant of proportionality.
We can define:
- x = number of hours that he charges the suit,
- y = number of hours that he can fly.
Now we know that if Abdul charges the suit for 1 hour, he can fly for 2 hours, then we have the pair:
Replacing that in the proportional relationship we get:
2 = k*1
Now we can solve this for k:
2 = k*1
2/1 = k = 2
From this, we can conclude that the proportional relationship is:
y = 2*x

1/4 y = 13
y = 13 x 4
y = 52
answer is C. 52
Answer:
Ok?
Step-by-step explanation:
We have

so this is indeed a difference of squares. Factorizing would give

making the answer D.
We can further factor the first term here and write

but that's clearly out of the scope of this question.
