Sometimes I’m pretty sure
To do this problem you would first need to factor out a variable, which in this case I would want to do the first equation because it is isolated. Now the equations would look like this:
x = -2y - 1
4x - 4y = 20
Since we know that x is now equal to -2y - 1 we can plug it in to the x value in the second equation:
4 (-2y -1) - 4y = 20
-8y -4 - 4y
-12y - 4 = 20
-12y = 24
y = -2
Now that we know the y value plug the y value to one equation to find the x, I will be using the first equation
x + 2(-2) = -1
x - 4 = -1
x = 3
Solutions:
y = -2
x = 3
Hello there.
What is the volume of the given prism?
9.4 * 5.4 * 11.7=<span>593.892

Round to the nearest tenth of a centimeter
Based off that,
Answer: 593.9.
Second Option.
Hey there!
These are technically expressed as fraction. When you divide a fraction by another, you can replace the second fraction with its reciprocal and you can now multiply the fractions together instead.


Now, just multiply across the top and the bottom. You can first cancel out any terms that are repeated or similar.
