Answer:
Step-by-step explanation:
The roof is made up of 2 similar pieces of 2 rectangle shapes.
----------------------------------------------------------------
Area of a rectangle = Length x Width
----------------------------------------------------------------
Area of a rectangle = 50 x 14 = 700 ft²
----------------------------------------------------------------
Area of 2 rectangle pieces:
----------------------------------------------------------------
Area of 2 rectangle pieces = 700 x 2 = 1400 ft²
----------------------------------------------------------------
Find the cost:
----------------------------------------------------------------
1ft² = $2.75
1400 ft² = 2.75 x 1400
1400 ft² = $3850
---------------------------------------------------------------------------------------------
Answer: It will cost $3850 to have the roof replaced. (Answer A)

Answer:
10 children
Step-by-step explanation:
If we have a ratio of 2:1 children:adults, then we can find out how many children max can enroll if there are 5 adults.
Our original ratio was 2:1 and now it's x:5, assuming x is the number of children enrolled. We multiply 1 by 5 to get to 5, so we need to multiply 2 by 5 to get the total number of chlidren.
2 × 5 = 10
Hope this helped!
Answer:
x= -3/2
Step-by-step explanation:
You would multiply both sides by 6x+10 and then that would give you 5-5)6x+10) and you would divide both sides by 5. This would give you 1=6x+10, you would then try to isolate the 6x giving you -6x=10-1 or -6x=9 and you would see if the solutions are in the defined ranges so x=-5/3 is NOT in the defined range but x=-3/2 is.
