Answer:
x = A/7
Step-by-step explanation:
Given that the screen is rectangular, recall that the area A of a rectangle whose length is L and width is W is given as
A = L * W
Hence if the width is 7 inches and the length is x inches then the area which is A square inches is connected to both sides as
A = x * 7
Divide both sides by 7
x = A/7 inches

.75% .0075 of the people that went to the concert said they would go if they could not see the band again. To find this you simply divide 9 by 1200, which equals .0075
6x = 90
x = 90/6
x = 15
4x + 10y = 90
4(15) + 10y = 90
60 + 10y = 90
10y = 30
y = 3
Answer: Last option
x = 15, y = 3
