You haven't posted the answer choices, but Trey got the wrong answer.
The denominators must be the same in order to add the fractions. In this case, the denominators 15 and 10 are different. We cannot add in this current state.
Adding the denominators is a common mistake which you should practice to avoid.
4.)
To solve for Y it is To solve for X
-8y=-6x -8y=-6x
/-8 /-8 /-6 /-6
y=3/4(x) 4/3(y)=x
5.)
to solve for Y To solve for X
1/2(y)=4(2x-1/4) 1/2(y)=4(2x-1/4)
1/2(y)=8x-1 /4 /4
*2 *2 y/8=2x-1/4
+1/4 +1/4
y=16x-2 (y/8)+1/4=2x
/2 /2
((y/8)+1/4)/2=x
Answer:
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction. Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia
