(base x height)/2 good luck young one
Answer:
76 degrees
Step-by-step explanation:
GE = 180 since it is a straight line
GE = GR + FE
180 = 7x+6 +6x-8
Combine like terms
180 = 13x-2
Add 2 to each side
182 = 13x
Divide by 13
182/13 = 13x/13
14 =x
We want FE
FE = 6x-8
FE = 6(14) -8
=84 -8
=76
The ad cost for half page Saturday after discount is
15% of 380 = 0.15×380 = 57
380 - 57 = 323
The ad cost for half page Tuesday after discount is
15% of 330 = 0.15×330 = 49.5
330 - 49.5 = 280.5
Cost of the ads for 10 Saturdays and 10 Tuesdays
(10×323)+(10×280.5) = 3230+2805 = 6035
