The answer is 6. You can show working by doing:

a/3 = a-2/2

Cross multiply to give you:

2a = 3(a-2)
2a = 3a - 6
-a = -6

So a = 6

A text font fits 12 characters per inch. Using the same font, how many characters can be expected per yard of text? NOTE: 1 yard
Sever21 [200]
432 characters can be expected to fit per yard of text. The following solution can be used:
Let x be the number of characters to be used in a yard
12 characters / in = x/ 36 in
(12 characters * 36 in) / in = x
x = 432 characters

Thank you for posting your question. Please feel free to ask me more.

Rewrite the expression in terms of sine and cosine, and simplify as much as possible. (sec w(1+ csc^2 w))/(csc^2 w)​
creativ13 [48]

Answer:

(sin^2 w + 1) / cos w.

Step-by-step explanation:

Note: sec w = 1 / cos w and csc w = 1/ sin w.

So we have:

(sec w(1 + csc^2 w)) / (csc^2 w)​

= 1/cos w (  1 + 1/ sin^2 w)  /   (1 / sin^2 w)

= ( 1/ cos w + 1 / sin^2 w cos w) * sin^2 w

=  sin^2 w/ cos w + sin^2 w / (sin^2 w cos w)

= sin^2 w / cos w + 1 /  cos w

=  (sin^2 w + 1) / cos w.
