Answer:
11/20 = 55%
Step-by-step explanation:
We should convert the percent into a fraction.
When simplified, we get the same value as the fraction on the left side of the inequality.
a2+b2=25
or, (a+b)^2-2ab=25
or, (7)^2-2ab=25 [a+b=7]
or, 49-25=2ab
or, 24/2=an
•°• ab=12....
D. 16.8
third option both cost the same after 2 months
B. (2 + 5).
18 + 45 = 63
The prime factors of 63 = 3*3*7
So 63 is a multiple of 7.
The answer is (2 + 5) (=7).
