Answer:
2 step equation problems.
Step-by-step explanation:
So you need to replace -3 into that to add -18 on both sides and that gives you the negative number is -20 and then you add the -5r+-3r less than or equal to -20. Now, negative -5 +3 = -8 + -20 = -28. r=-28.
We use rulers obviously because the length of rulers are about 4 more times longer than hands. Hope this helps you :]
The answer o this question would be:
<span>A.The vertical line test may be used to determine whether a function is one-to-one
</span><span>D. The horizontal line test may be used to determine whether a function is one-to-one.
Vertical and horizontal line test can be used to find out whether the function, not one-to-one. The test is done by making a horizontal line (for horizontal line test) or vertical line( for vertical line test). If there are no 2 or more points of the graph that touch the line in both tests, then the function would be one-to-one</span>
2x+5=77.
-5. -5
2x. = 72
2. 2
x= 36
to check all you do is plug in 36 into x
so you get 2(36)+5 which equals 77.
2x is the permed
5 is for lunch
77 total money they have
