Would the next step then be? 2c -13 +1c = 3c -13 = 66 then minus 66-13?

Age question: Kari's age is 13 less than twice Jackie's age, C. If the sum of their age is 66, find each person's age. 2c-13 = Kari 1C = Jackie Would I sent up this question as 2C-13+1C = 66?

Problem that I am not sure that I am doing right One hundred dollars was divided between Ann and Sandy. If Ann received X dollars, write expression for the amount that Sandy would relieved. Would it be 200 - X or 200/X?

** You mentioned combine like terms. You got 0.965x - how did you get that? Probably very dumb question - - - Updated - - - I just practiced on the problem - did you treat (x) as 1?

When you divide a fraction, you minus the exponent - correct? Example: x^9/x^4 you take the 9-5 = 5 so it would be x^5 -correc?

Sorry - The question is : How long did each person spend on their treadmill?

This problem has me stumped Jane and Terry used two different treadmills to exercise. The total distance waled between them was 10.35 miles. Jane waled at a pace of 4.9 per hour and Terry walked the pace of 4.5 per hour. Their total time as 3.5 hours. This is how I would set it up, but not...

*** I would take x-0.035x = 4120 then I would add x -0.035x(+0.035x) = 4120 +0.035 4120 + 0.035 = 4120.03?

I am wondering if I am starting this question the right way... As of Jan, the average tax refund sent to individual fliers was \$4,120 down 3.5% from last year. What was the average tax refund last year? Would the formula to start the problem be: x - 0.035 = \$4120? Any suggestions would be...
