What is 2x(y+5)=2.5y<br> What is 2x(y+5)=2.5y

White raven [17]

Answer:

simplify: 2.5 =(y+5)

reorder the terms: 2.5y=(5+y)

remove the parenthesis: 2.5y=5+y

solving: 2.5y=5+y

move all terms containing y to the left, all other terms to the right.

add -1y to each side of the equation

2.5y+-1y=5+y+-1y

combine like terms 2.5y+-1y=1.5y

1.5y=5+y+-1y

combine like terms: y+-1y=0

1.5y=5+0

1.5y=5

divide each side by 1.5

y=3.333333333

simplifying

y=3.333333333

Elena runs for 28 seconds and finishes at 250 seconds what is her velocity please explain

ExtremeBDS [4]

Answer:

The velocity is 8.93 meters/second.

Step-by-step explanation:

It is given that Elena runs for 28 seconds and finishes at 250 meters.

Here the displacement is 250 meters and the time is 28 seconds.

We know that $V=\dfrac{\text{Displacement}}{\text{Time}}$

Substitute displacement = 250 and time = 28 in above formula.

$V=\dfrac{250}{28}$

$V\approx 8.93$ meters/second

Hence, the velocity is 8.93 meters/second.
