Answer:
Step-by-step explanation: You multiply 3 by 20 so you multiply 20 by 20 to get 40
Answer 40:60
It is volume. The density would be far greater for the books and the atoms as well probably. But volume is just the length x width x height or something.
Answer:
Within 52 weeks, the amount of water in the two fish tanks will be the same.
Step-by-step explanation:
First, let's make the two equations equal to each other by placing an equal sign.
832 - 5x = 1040 - 9x
Now, that they are equal to each other, we can solve for x.
Okay, so we can move -5x to the other side by adding both sides with 5x.
832 = 1040 - 4x
Then, subtract 1040 from both sides to move it to the other side.
832 - 1040 = -208
-208 = -4x
Lastly, divide both sides by -4 to get the value of x.
-208/-4 = 52
x = 52
-3(4-2y)=24
distribute the -3
-12+6y=24
add 12 to both sides
6y=36
divide 6 on both sides
y=6
The number at the end of the equation shifts the graph up or down.
Changing the 1/2 to a -2 would shift the graph down which would change the y-intercept.
The answer is D.
