Answer:

Charlie would take 72 minutes to run 9 laps

Step-by-step explanation:

To get 9, multiple 2 by 4.5 which will equal 9

Then you multiply 16 by 4.5 which is 72

2 laps = 16 minutes so that's why we used those numbers for an example

Solve the system of equations by substitution <br><br> y = 2x + 1 and 3x + y = 16
Luden [163]

Answer:  y=7,x=3

Steps:

y = 2x + 1

3x + y = 16

Substitute y = 2x + 1

3x + 2x + 1 = 16

Simplify

5x+1=16

Isolate x for 5x + 1 = 16: x = 3

For y = 2x + 1

Substitute x = 3

y = 2 · 3 + 1

Simplify

y = 7

The solutions to the system of equations are:

y = 7, x = 3

Hope This Helps!

At t=0, a rock is dropped from rest from the top of a building 256 ft high. With what velocity will it strike the ground? What i
Rasek [7]

Answer:

128 ft / second.

Step-by-step explanation:

It's acceleration is due to gravity and is 32 ft s^-2.

To find the velocity when it hits the ground we use the equation of motion

v^2 = u^2 + 2gs    where  u = initial velocity, g = acceleration , s = distance.

v^2 = 0^2 + 2 * 32 * 256

v^2 = 16384

v =  128 ft s^-1.
