x in terms of b:

-2(bx - 5) = 16

-2bx + 10 = 16

-2bx = 6

x = 6 / -2b

x = -3/b

--------------------------------

when b = 3 then

-2(3x - 5) = 16

-6x + 10 = 16

-6x = 6

x = -1

Answer

The value of x in terms of b is -3/b

The value of x when b is 3 is -1

The base of a bicycle ramp has an area of 4 square feet. The ramp is a triangular prism. If the ramp has a height of 2 1/2 feet,

Anastaziya [24]

Answer:

Step-by-step explanation:

In general:

Volume = (the area of the base of the figure) times (the figure's height)

Here, the area of the base is 4 square feet, the height is 2 1/2 foot = 5/2 foot

Our Volume is then:

4 square feet * 5/2 foot = 10 cubic feet
