A = 0.50j + 6.......u r correct
he started with 6....and he is selling each cup (j) for 0.50
so lets say he sold 10 cups...u would sub in 10 for j
A = 0.50(10) + 6
A = 5 + 6
A = 11......and he would have $ 11

Answer:
Height of the building ≈ 947.34 ft
Step-by-step explanation:
Jack eyes are 5 ft above the ground .He is standing 500 ft from the base of a building .His line of sight forms angle with the top of the building at 67°. The height of the building can be computed below.
The illustration forms a right angle triangle. The opposite sight of the triangle is the unknown. The height of the building can be found by using the tangential ratio.
adjacent = 400 ft
angle = 67°
tan 67° = opposite/adjacent
tan 67° = a/400
cross multiply
a = 400 tan 67°
a = 400 × 2.35585236582
a = 942.34094633
Adding 5 ft to the total height of the building will be 5 + 942.34094633 = 947.34094633
Height of the building ≈ 947.34 ft
The like terms in this problem are the 10x and the 3x, as well as the 5 and 1. The 10x and 3x combine to get 13x, and the 5 and 1 add to make six.
Answer:
width= 27 ft, length=78 ft
Step-by-step explanation:
P=2l+2w
210=2l+2w
Divide by 2
105=l+w
l=5w-57
Substitute for l
105=6w-57
6w=162
w=27
l=5(27)-57
=135-27
l=78
