Think of it as (-4x+1)(3x+2) then distribute: -4x x 3x= -12x^2, -4x x 2= -8x, 1 x 3x = 3x, and 2 x 1=2. put together all the answers we just got so: -12x^2 - 8x +3x +2 then simplify to get -12x^2 -5x +2

Fred is running on the school track. He can run 10 3 4 laps in 4 5 of an hour. How many laps can Fred run in one hour?

Triss [41]

Answer:

$13\frac{7}{16}$ laps can Fred run in one hour.

Step-by-step explanation:

Given Statement: Fred is running on the school track. He can run $10\frac{3}{4}$ laps in $\frac{4}{5}$ of an hour.

Unit rate are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates

From the given condition we have;

In $\frac{4}{5}$ he can run $\frac{43}{4}$ laps

Unit rate per hour = $\frac{\frac{43}{4} }{\frac{4}{5} }$

= $\frac{43}{4} \times \frac{5}{4} = \frac{215}{16}$ laps

Therefore, Fred can run in one hour is, $13\frac{7}{16}$ laps.
