A + 5 > -7....subtract 5 from both sides
a > -7 - 5
a > - 12
Subtract 2 from both sides and you get 2x>2, dived 2 from both sides to isolate the variable. Then you get x>1 :)
Answer: 1 & 1/2
The whole part is 1
The fractional part is 1/2
======================================================
Explanation:
Write 1/2 as 2/4. Basically you multiply top and bottom by 2.
We have these three fractions: 1/4, 2/4, 3/4
Add them up: (1/4)+(2/4)+(3/4) = (1+2+3)/4 = 6/4 = 3/2
To go from 6/4 to 3/2, we divide both parts by 2.
Finally, convert the improper fraction 3/2 to the mixed number 1 & 1/2
30cm cubed the formula is v=bh
