C. 60 unit cubes.
Each level has 20 unit cubes, times 3 is 60 in total.
This is quite simple, you can see that the x-axis stays the same so then you know that it is a vertical line. You can tell because any point on this line will be (2,x). So to graph it, you draw a vertical line where x=2
Answer:
(4, 7) (third answer choice)
Step-by-step explanation:
In the system
y = x + 3
3x + y = 19
the first equation already gives y in terms of x. Thus we can substitute x + 3 for y in the second equation:
3x + (x + 3) = 19, which simplifies to:
4x = 16, yielding x = 4. Substituting 4 for x in the first equation, we get:
y = (4) + 3 = 7.
Thus, the solution is (4, 7) (third answer choice).
We need to simplify it as there is no definite answer without knowing the value of <em>x. </em><span><span><span>2.5x</span>+<span>0.1x</span></span>−<span>0.01x</span></span><span>=<span><span><span><span>2.5x</span>+<span>0.1x</span></span>+</span>−<span>0.01x </span></span></span>Find the like terms:<span>=<span><span><span>2.5x</span>+<span>0.1x</span></span>+<span>−<span>0.01x
