1) What distance did a car travel that went 70 mph for 6 hours?

Given:

70 miles = 1 hour

Multiply the RHS by 6 to see what distance was covered by the car in 6 hours.

70 miles = 1 hour
=> 70 x 6 miles = 6 hours
=> 420 miles = 6 hours

The car traveled 420 miles in 6 hours.

2) What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?

Given:

Length: 7 cm
Breadth: 4 cm

Formula to find perimeter: 2(L) + 2(B)

Substitute the values into the formula to find the perimeter.

2(L) + 2(B)
=> 2(7) + 2(4)
=> 14 + 8
=> 22 cm

The perimeter of the rectangle is 22 cm.

The teacher said that both equations were correct. Explain why?

anyanavicka [17]

Because they are the same equation, just rewritten in a different way.

s = 4p

divide both sides by 4 to get the other equation:
(1/4)s = p

At a sale this week, a desk is being sold for $336. This is a 36% discount from the original price.

8090 [49]

Answer:

$525

Step-by-step explanation:

We can find the original price by using the formula x - 0.36x = 336, where x is the original price, 0.36 is the discount percentage (converted to decimal form), and 336 is the total amount paid after the discount is applied:

$x-0.36x=336\\0.64x=336\\x=525$

To check and further understand why the formula works, we can simply apply the discount to the original price and subtract the number from the original price:

525 * 0.36 = 189

525 - 189 = 336

Modeling the first formula gives us:

525 - (0.36 * 525) = 336

525 - 189 = 336
