Answer:
Step-by-step explanation:
Here is a tip: When you have something that looks like this - ( - , turn it into a plus sign. It looks kind of like a plus sign anyway. So if you have 53- (-32), turn it into 53 + 32. Does that make sense?
So 53 + 32 = 85.
Another tip to do it in your head, is to do 50 + 30 = 80, then do 3 + 2 = 5, and add them. It's easier than trying to juggle the odd numbers. :)
The answers should be: (-2,5), (-2,-2), (-6,-1), (2,1)
Hope this helped :)
Answer:
It's 4x - 8 + 4y
Step-by-step explanation:
4(x-2+y)
4 (x) = 4x
4 (2) = 8
4 (y) = 4y
4x - 8 + 4y
3x(1.05) = 3.15x
1.05x + 1.05x + 1.05x = 3.15x
The fraction 6/3 is equivalent to 2. So, it's a integer number once the numerator is multiple of the denominator.
