18/10
9/5
Anything along those lines!
X = 2 + 4y
67 = x + y
67 = (2 + 4y) + y = 2 + 5y
65/5 = 13 = y
67 - 13 = x = 54.
x = 54
y = 13.
The selling price of 18 shirts is given by g(f(18))
g(f(x))= 5.f(x) + 6= 5[(5/6)x+5]+6=(25/6)x+25+6
g(f(x))=25/6)x+25+6
g(f(18))=25/6).18+25+6=106
the answer is 106
Answer: 26/21 or 1 and 5/21
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by the reciprocal, so you can rewrite this problem as (4/6) x (13/7)
Next, multiply the numerators (4 and 13) and the denominators (6 and 7)
You will get 52/42, which can be simplified to 26/21 (you can also write this as 1 and 5/21)
Hope this helps
