write out the equation:
8y=3+7y (I'm assuming y is the amount of comic books)
8=3+7
8=10
Obviously the equation isn't equal. The nonfiction is greater. By the way, I took out the y because I assumed that y was the amount of books and there was no need to write out 8 times one. On a test, make sure you specify this of the teacher may take off points, if she is using Common Core.
Answer:160 B.
Step-by-step explanation: first you seperate the two rectangles. then find volume of both by multipling lenngh times with times height then add both of your volumes.
15+c=17.50
First you subtract 15 by 15 because you switch operations from adding to subtracting then you would put C under it
Second subtract 17.50 and 15 and that is 2.50 so C= 2.50
If the submarine descended 184.4 meters in 23.5 minutes, its rate of descent was ...
... (184.4 m)/(23.5 min) ≈ 7.847 m/min
The submarine descended about 7.85 meters in one minute.
Y = 2x - 10
y = 4x - 8
2x - 10 = 4x - 8
2x - 4x = -8 + 10
-2x = 2
x = -2/2
x = -1
y = 4x - 8
y = 4(-1) - 8
y = -4 - 8
y = -12
solution is (-1,-12)
