Answer:
5 hours
Step-by-step explanation:
Set up an equation where y=total cost and x= hours
y=7x+15
Substitute 50 for y, the total cost, and solve for x, the total hours
50=7x+15, Subtract 15 from both sides
35=7x, Divide both sides by 7 to get x alone
x=5

A. This is because for symmetry both sides of the symmetry line need to be the same. Choice A is the only one that fulfills that requirement.
Step-by-step explanation:
For a given rectangle,the area(A) is the product of its length and width
A=lw, given A=350m² and l=50m
transposing the equation for w gives w=A/l
w=350m²/50m=7m
That's it
