There is a problem with this question.
if 15 students is 92% of the class, the total class size is therefore
N=15*(100/92) = 16.3, or 16 students (to the nearest integer).
So far so good.
However, if we check back, 15 students out of 16 is 15/16*100%=93.75%, nowhere near 92%. I have no idea where the 92% came from, and hence I doubt if there might not be a typo, by the submitting user, or the teacher.
Answer:
(x-5) (x+4)
Step-by-step explanation:
x^2 -x -20
What two terms multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
(x-5) (x+4)
The correct option of your question is D
Step-by-step explanation:
To solve the sum we need to understand the distributive property
a×(b+c) = a×b + a×c
Here,
Option D is given as
RHS = 5(3+8) [ a=5, b=3 and c=8]
=15 + 40
= LHS
It satisfies the distributive property.
You can cross check the property with the other options.
D is the correct option.
Well, the answer would bee 1/10 for a simple reason: the 3 in 7.315 is in the tenth's spot while the 3 in 893.5 is in the ones. a one spot different that can be proven with logic.
4.312, 4.316, 4.32, 4.5
I hope this helps ^W^ have a great day!
