Answer:
You haven't given the numbers for us to find the numbers place in. Here are my examples of the place values that "7" could be in:
17- ones
71- tens
711-hundreds
7,111-thousands
71,111-ten thousands
711,111-hundred thousands
7,111,111-one millions

Miles driven per hour is 60 miles per hour
Hours driven per mile is 0.01667 hours per mile
<em><u>Solution:</u></em>
Given that,
On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours
Therefore,
Miles driven = 210 miles

To find: miles driven per hour and the hours driven per mile
<h3><u>Miles driven per hour</u></h3>

<h3><u>Hours driven per mile</u></h3>

Thus both the miles driven per hour and the hours driven per mile are found
Add the length and width of rectangle A and set equal to the sum of the length and width of rectangle B.
Then solve for d.
Once you know d, substitute it in each length and width to find the actual lengths and widths.
0.7d + 1 + 1.5d - 2 = 2.5 + d + 4 - 1.3d
2.2d - 1 = -0.3d + 6.5
2.5d = 7.5
d = 3
Rectangle A:
Length: 0.7d + 1 = 0.7(3) + 1 = 2.1 + 1 = 3.1
Width: 1.5d - 2 = 1.5(3) - 2 = 4.5 - 2 = 2.5
Rectangle B:
Length: 2.5 + d = 2.5 + 3 = 5.5
Width: 4 - 1.3d = 4 - 1.3(3) = 4 - 3.9 = 0.1
