Answer:

5 $20 bills and 7 $10 bills

Step-by-step explanation:

You need to have 12 bills, and their values must add up to $170. Start with a guess, and adjust the guess until you find the answer.

The total number of $20 bills and $10 bills must be 10.

I made a table below. I started with a guess and kept adjusting it.

Number of          Number of          Total

$20 bills               $10 bills               Value

8   ($160)              4    ($40)              $200      Value is too high.

6   ($120)              6    ($60)              $180       Value is close

5   ($100)              7    ($70)               $70        Correct value

Answer: 5 $20 bills and 7 $10 bills

Shanna is planning a trip from Dallas, Texas, to San Diego, California.

She will travel about = 1,400 miles

Eric made a drawing of his rectangular bedroom with the scale 1 inch=3 feet. The drawing was 5 inches long 4 inches wide. What w
kolbaska11 [484]

Answer:

180 square feet

Step-by-step explanation:

We know that the rectangular drawing has:

  • 5 inches long (L)
  • 4 inches wide (W)

And we also know that:

<em>1 inch = 3 feet</em>

We will find how many feet long and wide is the actual room, by multiplying:

Long: 5 inches * 3 feet/inch = 15 feet

Wide: 4 inches * 3 feet/ inch = 12 feet

Now we want to know the area of the rectangle, and the area of the rectangle is:

<em>A = L*W</em>

<em>A = 15 feet * 12 feet</em>

A = 180 square feet

Draw the shape by drawing dots at the co-ordinates. 
Connect them in order, so if it's KLMN, connect K to L then to M then N.
Then, pick one of the points, I'd choose K, then move that dot 3 to the right, then move it 4 up. Do the same for all of the letters.
