Answer:

y = 20 - x

Step-by-step explanation:

Perimeter of a rectangle = 40 units

2 * ( length + width) = 40

2* (x + y) = 40 {Divide both sides by 2}}

x + y = 40/2

x + y = 20 {Subtract x from both sides}

y = 20 - x

At 5:00 a.M., a parking lot had 16 cars already parked in it. Throughout the course of the day, 48 more cars entered and parked

Alekssandra [29.7K]

Answer:

The situation is that; the parking lot has 64 cars at the end of the day

Step-by-step explanation:

Given

Initial Number of cars = 16

Additional Cars = 48

Required

Determine the situation for the day

From the question, we understand that no car left the park;

This implies that

$Number\ of\ cars = Initial\ Cars + Additional\ Cars$

$Number\ of\ cars = 16 + 48$

$Number\ of\ cars = 64$

<em>So, the situation is that; the parking lot has 64 cars at the end of the day</em>

Explain how finding 4x384 can help you find 4x5384

yulyashka [42]

Well the 384 part is the harder part because it is a more complex number (for humans) so after you find out what 4x384=(1536) then 4x5000 is simple and you just add the two answers together.
