Answer:
x=82
Step-by-step explanation:
53+45=98
180-98=82
Step-by-step explanation:
4
Add all to get 32
Divide by the number of items which is 8
answer =4
7/5 = 14/10 = 28/20
Numerator = x
Denominator = x-4
Add 3 to both:
x +3 / (x-4+3)
x+3 = 14
(x-4 +3) = 10 = x-1 = 10
x = 11
Check:
11 -4 = 7 ( denominator is 4 less than the numerator.)
add 3 to both:
11+3 = 14
7+3 = 10
14/10 reduces to 7/5
The original fraction would be 11/7
Given:
The given expression is:

To find:
Part A: The expression by factoring out the greatest common factor.
Part B: Factor the entire expression completely.
Solution:
Part A:
We have,

Taking out the highest common factor 3y, we get

Therefore, the required expression is
.
Part B:
From part A, we have,

By grouping method, we get


Therefore, the required factored form of the given expression is
.
This is simple proportions, because of their similarity:
