Use the equation=
x^2+5^2=9^2
x^2+25=81
x^2+25-25=81-25
x^2=56
$\sqrt{x} = \sqrt{56}$
x=7.48331477355

andre rode his bike at a constant speed he rode 1 mile in 5 minutes which of these equations represents the amount of time in mi

Alex777 [14]

We are given

Andre rode his bike at a constant speed he rode 1 mile in 5 minutes

Firstly, we will find constant speed

In 5 minutes , distance travelled =1 miles

so, we get speed

$v=\frac{1}{5} mile/min$

Let's assume T is time in minutes

D is the distance in miles

we know that

$Time=\frac{Distance}{speed}$

so, we can plug value

and we get

$T=\frac{D}{\frac{1}{5} }$

so, we get

$T=5D$ ...............Answer

What are the side lengths of the equilateral triangle?

Alchen [17]

$5x + (6x - 5) + (3x + 10) = 360$

$5x + 6x - 5 + 3x + 10 = 360$

$11x - 5 + 3x + 10 = 360$

$14x + 5 = 360$

$14x = 360 - 5$

$14x = 355$

$x = 25.36$

$x = 25.36$

$5x = 5 \times 25.36 = 126.8$

$6x - 5 = 6 \times 25.36 - 5 = 147.16$

$3x + 10 = 3 \times 25.36 + 10 = 86.08$
