First,you do,2/5+2/3,but since you will need a common denominator,you will find the least common denominator for 5 and 3.The LCD(Least Common Denominator) will be 15 since both 5 and 3 could go in 15.Now,the equation looks like this: 2/15+2/15 since whatever you do to the bottom numbers,you NEED to do to the top numbers:2 and 2.Now you will need to do,2x3,since 5x3=15 and the answer to 2x3=6 then you do 2x5,since 3x5=15 the answer is 10 now the equation looks like this:6/15+10/15 now you add them together,and the answer will be 16/15 and if you want the answer to be a mixed number,it would look like this: 1 1/15. Hope this helps!
Answer:
V=a^3
Step-by-step explanation:
The volume of a cube is found by multiplying the length, width, and height. A cube has the same length, width and height. In this case is it 9, so you multiply 9 by 9, three times, obtaining 729, which is your volume.
V=9^3
9x9x9
V=729
Answer:
Ur right! The answer is y = 6
Step-by-step explanation:
So, we have the equation of -2y + 7 = -5.
So, if y = 6, it would now be (-2 * 6) + 7 = -5.
Now, lets solve:
(-2 * 6) + 7
-12 + 7
= -5
So, ur answer is A. y = 6.
Hope this helps :DD
