Given that the table shows the total miles Uyen has run this week.
The image of the table is attached below.
The total distance from the table is
The total distance this week is 1.5 times the distance that she ran last week.
We need to determine the number of miles that Uyen run last week.
<u>The number of miles Uyen run last week:</u>
Let x denote the number of miles that Uyen run last week.
Let us write the equation from the given data.
Thus, we have;
Dividing both sides by 1.5, we have;
Hence, the value of x is 14.8 miles.
Thus, Uyen ran 14.8 miles last week.

Step-by-step explanation:
The circumference of a circle is the distance around the circle, or the perimeter. It is the product of pi and the diameter.
The diameter is the distance from one side to the other through the center. If we look at the circle given, we see the diameter must be 52 yards.
- d= 52 yd
Also, remember we are using 3.14 for pi.
= 3.14
Substitute these values into the formula.
Multiply.
The circumference of the circle is <u>163.28 yards.</u>
