Answer:
y= 2x + 85
y= $555
x= $235
Step-by-step explanation:
Let y be the amount the senior class raised
Let x be the amount the freshmen class raised
Insert known values
$555 = 2x + $85
Subtract 85 from both sides
$470 = 2x
Isolate the variable (x) by dividing each side by 2
$235 = x
Hope this helps! :)

Answer:
Height of the awning = 9.52 feet
Step-by-step explanation:
For better understanding of the solution, see the attached diagram of the problem :
According to the figure, AB is the height of the awning
Now, the base of awning will be perpendicular to the building
⇒ m∠ABC = 90°
In ΔABC, By using angle sum property of a triangle
m∠ABC + m∠ACB + m∠BAC = 180°
⇒ m∠ACB = 50°
Hence, Height of the awning = 9.52 feet
