1. 0.25. This is because if you have -18.75 and then you add 20 to it you would be left with 0.25.
2. -1.25. This is because if you add AM and Noon together you would get that answer.
3. 14.1. If you do 1.43 + 12.67 then you would get that answer.
Point slope form: y-y-coordinate=slope(x-x-coordinate)
slope intercept form: y=mx+b
standard form: x + y=
1. 7x + 9 = 48
7x = 58 - 9
7x = 49
X = 7
Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
