Answer:
Hi,
a=b+3
Step-by-step explanation:
Thus:
c+2b+8-4a=c-a-b-1
3b-3a=-9
<u>a=b+3</u>
The amount of girls in the club is 18 out of the 32 members.
To find the amount of boys there, we subtract 18 out of 32
32 - 18 = 14
so there are 14 boys in the club
Now to find the ratio of girls to boys...
18/14
simplified to 9/7 (option D.)
Hope this helps :)
Answer:
A choice
Step-by-step explanation:
sec is defined as 1/cos.
cos is again defined as adjacent to hypotenuse.
We know that adjacent is x and hypotenuse is r.
Therefore:- cos is x/r
Now sec is 1/cos = 1/(x/r)
1 ÷ x/r is 1•r/x
Thus:-
sec is r/x
