3s is 3 times sydneys age. so the equation would be 3s-5
Answer:
it is becuse you do 13-4 which would give you nine.
The estimated answer is 11. First you round 16.8 to 17 because the decimal is above 5. Then you round 5.94 to 6 because the first decimal place is greater than 5. Lastly you subtract 17 minus 5 to get 11.
-4(-5) = -4*-5 = 20
6 - (-4) = 10
Quotient = 20 /10 = 2 answer
