actually i need help on this question 2 :p lol
The sum of 3 plus 4 is 7.
f = -6
2f-6=4 2f-6=4 (add 6 to both sides) +6 +6 2f=10 (divide by 2) -- --- 2 2 f=5 (the 2s cancel out and 10/2 is 5)
0.75
4 and -1 have a product of -4 and a sum of 3.
4/3.
75 - 4% = 72, so therefore 4% of 75 is 3
-2
7
What is the sum of greatest 3-digit 4-digit 5digit
1 + 3 = 4
It is: 3*(4+12) = 48
