Answer:
Jonah only added two sides together instead of all four sides
Perimeter = 12 x - 6
Step-by-step explanation:
P = 2(6x - 5) + 2(1/4x + 2)
P = 12x - 10 + 1/2x + 4
P = 12 1/2x - 6
Answer:
c. 6
d. 3
Step-by-step explanation:
:-)
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
