Answer:
x = 3
Step-by-step explanation:
5x + 4x = 9x
27 / 9
3
(-X-13)+(X+13)+(X-13)
The positive x and negative x cancel out and equal zero. The positive 13 and negative 13 cancel and equal zero also. Then you are left with (x-13)
Answer:
480 in3
Step-by-step explanation:
So the first thing I looked at was how to find the volume of a 3-dimensional square. Why do we have to do this? Well, we can see that the shape is made up of 3 different types of 3-dimensional cubes so to find the answer all we have to do is figure out the volume for each separate cube and add them all together.
So, to find the volume of a cube we have to multiply the area (length x width) by the height of each cube.
Let's start with the largest cube so we would multiply 5 x 12 x 4 which equals <u>v = 240</u>
Now let us do the second to largest by multiplying 8 x 5 x 4 = which equals <u>v = 160</u>
Finally, on to the smallest cube, 4 x 4 x 5 =
<u>v = 80</u>
So now if we add <u><em>240 + 160 + 80</em></u> that will give us 480
So the answer is <u><em>480 in3</em></u>
Hope this is correct I was a little confused while I was figuring it out :0 Sorry if it is wrong :(
So to solve this question, your goal is to find out how the way it is solved is not correct.
Your answer would be: On the third line, the student adds the 8 to both sides instead of subtracting. The way the initial equation is given is
y-(-8)=-6(x-2). After distributing the six, the student should make the 8 positive because subtracting a negative makes a positive. After solving, the equation should look like: y(+8)=-6x+12, so you would subtract the 8 from both sides instead of adding it, and solve from there.
