43.87 - 8 = 35.87 (sandals)
9.49 + 9.49 = 18.98 ( for two t-shirts)
35.87 - 18.98 = 16.89 (t-shirts)
16.89 - 2.87 = 14.02 (taxes)
Andrea payed $14.02 for a pair of jeans
Hopes this helps you!
It's the function of function: f(g(x))
1st you replace x (of f(x) by the value of g(x)
Example: let's take f(x) = x² ag g(x) = 1/x, you just plug 1/x into x in f(x)
f(g(x)) = f(1/x)² & f(x) =1/x²
If we follow the same methodology we find that f(x) =2/x & g(x) =2/x is the answer to the problem. Proof:
f(g(x)) = f( 2/(2/x)) = f(2(x/2) =2x/2 = x
Answer:
12 girls
28 boys
Step-by-step explanation:
Multiply 40 by 30/100 to get 12 girls.

Answer:
38.5 cm^2
Step-by-step explanation:
Area(shaded) = Area(large semicircle) - area(2 small equal semicircles)
= Area (large semicircle) - area (small circle)
= π(7)² x 1/2 - π(7/2)²
22/7 x 7 x 7 x 1/2 - 22/7 x 7/2 x 7/2
= 77 - 38.5
= 38.5 cm^2
