To do this we first have to find the unit rate of 2,600.
2,600/4=650 each week. Then, we just multiply 650x20, with 20 being the number of weeks.
650x20=13,000<---Answer

<u>Given:</u>
An isosceles trapezoid has a perimeter of 37 centimeters. Its shorter base measures 3 centimeters and its longer base measures 4 centimeters. The two remaining sides have the same length.
We need to determine the lengths.
<u>Length of the remaining sides:</u>
Let the length of the sides of the isosceles trapezoid be x.
Let a be the length of the shorter base.
Let b be the length of the longer base.
Thus, we have;

The formula to determine the length of the sides is given by

Substituting the values, we get;




Thus, the length of the sides of the isosceles trapezoid is 15 centimeters.
<span><u>8x + 9 = 5x + 18</u>
Subtract 9 from each side:
8x = 5x + 9
Subtract 5x from each side:
3x = 9
Divide each side by 3 :
<u>x = 3</u>
