Laura left Dunkin Donuts at 1 PM traveling 30 mph. Two hours later her friend Jen left the same Dunkin Donuts and started after
Wewaii [24]

Answer:

It took Jen 4 hours to catch up with Laura

Step-by-step explanation:

Gaining speed 45-30= 15 mph

Laura's head start 30×2=60 miles

Time for Jen to catch up 60÷15= 4 hours

In other words

30(t+2)= 45t

30t+60= 45t

60=45t-30t

60= 15t

t=4 hours

Explain why an elevator with 3 people in it is less dense with an elevator with 50 people in it
Harrizon [31]

Answer:

  it has a lower mass/volume ratio

Step-by-step explanation:

Density is the ratio of mass to volume. An elevator will have the same volume, regardless of the number of people. The mass will increase with the number of people.

An elevator with 50 people in it will have a higher mass/volume ratio than an elevator with 3 people in it. Hence the latter is less dense.

__

<em>Additional comment</em>

50 persons would require an industrial elevator of perhaps 10,000 pound load capacity. There might be safety issues with carrying that many people.

The graph below shows a system of equations:
Nostrana [21]
3y = -2x + 2
y = x + 4 (Substitute the y)

3(x + 4) = -2x + 2 (Distribute)
3x + 12 = -2x + 2 (Add 3 to both sides)
+3x       +3x
------------------------------------------
12 = 1x + 2 (Subtract 2 from both sides)
-2         - 2
------------------------
10 = 1x (Divide by 1 on both sides)
10/1 = 1x/1
x = 10 
This is your x-coordinate

What is the solution to the system of equations below?
Free_Kalibri [48]

Answer: Infinite solutions.

Step-by-step explanation:

y=-2x-6\\2y=-4x-12

Plug the value of y into the second equation.

\\ 2(-2x-6)=-4x-12\\-4x-12=-4x-12

Add 12 on both sides.

-4x-12+12=-4x-12+12\\-4x=-4x

Add 4x on both sides.

-4x+4x=-4x+4x

0=0
