A rectangular room is 3 meters longer than it is wide, and its perimeter is 26 meters. Find the dimension of the room. The length is : meters and the width is meters.

Perimeter is the sum of all 4 walls.

Divide the perimeter in half for the total of the width  + the length:

26/2 = 13 meters

Subtract the difference in length:

13 - 3 = 10

Divide by 2 walls:

10/2 = 5

The width is 5 metes.

The length is the 5 metes + the 3 meter difference = 5 +3 = 8 meters.

The length is 8 meters and the width is 5 meters.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
