Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
Approach 2: use a table again, but use variables instead of numbers (I prefer doing this, makes things easier and neater)
today | + 4yrs ------------------- R| 2S | 2S + 4 S| S | S + 4 T| S+3 | (S + 3) + 4 = S + 7
1. Is 2S + 4 equal to 2(S+4)? No. 2. Is Sam 3 years younger than Tina? Yes... (S + 7) (tina's age in 4 year) - 3 = S + 4 (Sam's age in 4 years) 3. Is Rose older than Tina? Not necessarily. Answer = No. I said not necessarily because if S = 2, then in 4 years R = 12 and T = 9 ... BUT IF s = 1, then in 4 years, R = 5 and T = 8... This is kind of like a D.S. question actually if you solve using algebra...
