Answer:
full page = 8
half page = 5
Step-by-step explanation:
two equations can be derived from the question
40x + 75y = 800 equation 1
x + y = 13 equation 2
x = number of half page advertisement
y = number of full page advertisement
multiply equation 2 by 40
40x + 40y = 520 equation 3
subtract equation 3 from 2
280 = 35y
y = 8
substitute for y in equation 2
x + 8 = 13
x = 13 - 8
x = 5
Answer:
A = 49 ft^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want the area
A = s^2
A = 7^2
A = 49 ft^2

Answer:
(f+g)(x)=4x+5
Step-by-step explanation:

(f+g)(x)=f(x)+g(x)=(10-2x)+(6x-5)=-2x+6x+10-5=4x+5
So (f+g)(x)=4x+5
