Answer:
A. 45h = 1,575
Step-by-step explanation:
Area of trapezoid = 1,575 cm² (given)
We are given the length of both bases, a = 63 cm and b = 27 cm
We need to find the formula that will enable us determine its height (h).
Thus:
Area of trapezoid = ½(a + b)h
Plug in the values
½(63 + 27)h = 1,575
½(90)h = 1,575
45h = 1,575
The answer is A. 45h = 1,575

Kelvin Doe is from a small village in the Republic of Sierra Leone in West Africa. Your welcome :)
First solve one of the two equations (whichever is easier) for either x or y, whichever variable is easier. Let's say you solved for x. Then plug what x equals into the 2nd equation as x. So if you got x = 2y + 1, plug that into your other equation and solve for y (you should get a number value).
Now take whatever y equals and plug that back into what you got when you solved for x (the x = 2y + 1) to get what x equals.
Answer:
4 Hours.
Step-by-step explanation:
Since they charge $5 for every hour, we can use 5(x) as our first variable, x being the number of hours that he rented the paddle boar. Also, since they charge $8 up front, we have to subtract that from the total cost , so it would be $28 - $8. After this we divide the result ($20) by 5, since our coefficient is 5, and it costs $5 to rent it every hour. This results in 20/5, and comes out to 4 hours in total.
