Oh. It's rounding. So, for example, depending what you were told to round to, the second problem would be 760-330=430
Answer: 1. 28 2. 25
Hope this helps!
Didn't know if you wanted the explanation or not, so sorry. But I can put an explanation if you need it.
The product of two rational numbers is rational is the correct answer
X(3y+2)-6(3y+2)
(x-6)(3y+2)
so the answer is 2+3y
Part a I am pretty sure it is a pattern so 4 plus 2 is 6, 6 plus 3 is nine and then 9 plus 4 is 13 Then 13 plus 5 is 18
Answer is 18
In part b he will not finish his work he has to get to 274 and he only gets to about 50 something
Hope this helps
