Well I'm still trying to solve the first question so I'll tell you the other answers
the answer for the second question is :

and for the third question :
Convert 79% to a decimal which is .79
Then you multiply .79 by 32 which is 25.28
Your answer is 25.28
Since it is an isosceles trapezoid;
AB=CD which means;
5y-3=6y-17
get the variables to one side and you get:
-3=y-17
Then add 17 to both sides and
14=y
Therefore y=14 is your answer
Answer:
y=4
Step-by-step explanation:
Area = Length x width.
Area of room = 15 x 24 = 360 square feet.
Now multiply the square feet by the cost:
360 x 5 = $1800
It will cost $1,800
