54/4.5 = 12
Set it up as long division, with 54 "inside" the division sign and 4.5 outside. Then you have to move the decimal on 4.5 to the right once, which will give you 45 on the outside. You also have to move the decimal over 1 more place on the 54, which will give you 540 on the inside. Then figure out how many times 45 can go into 54, which is once. Then subtract 45 from 54, which will give you 9. Then you are left with 90 on the inside and 45 goes into that 2 times.

EXPLANATION:
The slope-intercept form is where is the slope and is the y-intercept
Using the slope-intercept form, the slope is
hope it's helps
Plotting the points, you see that they lie on the same line: x=-3.
Therefore, you only need to find the distance between the y-coordinates.
6-(-1)=7, so therefore, Vicky's house is 7 units apart from her school.
The freight train speed = 22 mph
The passenger train speed = 28 mph
Step-by-step explanation:
Assign the speed of the freight train as; <em>x </em>mph
Since the passenger train travels 6 mph faster than the freight train, its speed will be; (<em>x + 6</em>) mph
In 2 hours, the freight and passenger trains will have traveled (distance = speed * time);
2<em>x</em> and 2(<em>x + 6</em>) miles respectively
Both add up to 100 miles. Therefore;
2x + 2(x +6) = 100
4x + 12 = 100
4x = 88
x = 22
x + 6 = 28
The freight train speed = 22 mph
The passenger train speed = 28 mph
