Answer:
(C) 2
Step-by-step explanation:
Given equations 2a + 7b+2c=16 and 2a + 3b +2c= 8, you want to know the value of b.
<h3>Solution</h3>
The coefficients of 'a' and 'c' are the same in the two equations, so we can eliminate those variables by subtracting one equation from the other. We can keep the resulting coefficient of 'b' positive if we subtract the second equation from the first.
(2a +7b +2c) -(2a +3b +2c) = (16) -(8)
4b = 8 . . . . . . . simplify
b = 2 . . . . . . . divide by 4
of students only saw jewelry collection
<em><u>Solution:</u></em>
Given that, On a class trip to the museum,5/8 of the students saw the dinosaurs
7/8 of the students saw either the jewelry collection or the dinosaurs
<em><u>To find: Fraction of students only saw jewelry collection</u></em>
From given statement,
Fraction of students saw dinosaur =
Fraction of students saw either the jewelry collection or the dinosaurs =
Therefore,
Fraction of students only saw jewelry collection = Fraction of students saw either the jewelry collection or the dinosaurs - Fraction of students saw dinosaur
Thus of students only saw jewelry collection
