1 answer:

5 0

Answer:

Step-by-step explanation: Since the question does not specify wether the temperature dropped every hour or if it was the total, in this case we can assume this was in total. If you ended up with -2 after subtracting 13, to get the starting temperature you can add -2 to 13.

-2 + 13 = 11

The length of a rectangle is twice its width. The perimeter of the rectangle is 30 cm. What are the length and width? a) Set up

Helga [31]

Answer:

10 cm and 5 cm

Step-by-step explanation:

a) Set up the variables:

Let x represent the width; Then 2x will represent the length.

b) What is the equation that represents the above situation?

Use perimeter formula:

P = 2( l + w)

As we set up w = x and l = 2x, and we know that the perimeter is 30 cm, we can build an equation by substituting the values we know or set up:

30 = 2( 2x + x)

c) solve the equation

30 = 2( 2x + x)
30 = 2(3x)
30 = 6x
x = 30/6
x = 5

d) the length and width are?

The width is 5 cm and the length is twice the width, 5*2 = 10 cm
