I’m not very good at math, but maybe try adding all of them together
Answer:
43% of the students prefer biology
Step-by-step explanation:
Among girls:
39 of the students are girls.
21 of the girls like biology best.
Boys:
100 - 39 = 61 are boys.
16 prefer physics
11 out of the 34 who prefer chemistry are girls, so 34 - 11 = 23 are boys.
61 - (16 + 23) = 22 prefer biology.
What percentage of the students prefer biology?
21 boys and 22 boys, that is, 43 students out of 100. So
43*100%/100 = 43%
43% of the students prefer biology
Answer:
Step-by-step explanation:
So basically the equation is (x+2) times (x+6). Use the FOIL method to multiply across like this:
x*x + x*6 + 2*x + 2*6
Combine like terms
x^2 + 8x + 12
Thank me later :)
BC means B times C
B=-4
C=2
B times C=-4 times 2=-8
Your number could be rounded to:
2.01
Hope it helped,
Happy homework/ study/ exam!
