Jessica is a custodian at oracle arena. she waxes 20m2 of the floor in 3/5 of an hour. jessica waxes the floor at a constant rate. at this rate, how many square meters can she wax per hour?

Step-by-step explanation:

Let be the rate at which Jessica waxes.

Let be the area which Jessica waxes in hours of time.

So,

Given that she waxes in hours.

To know how much area she sweeps in a hour,substitute for in the above equation.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
