To convert the distance that is given in yards to miles, we use the conversion factor,
1 yard = 0.000568 miles
which is also equal to
1 mile = 1760 yards
With these conversion factor we convert the given,
(2180 yards) x (1 mile / 1760 yard) = 1.24 miles
The absolute value would be 18 !
Set the Ys equal to eachother them solve for X
3x-13=-4x+1
+13 to both sides
3x=-4x+14
Add 4x to both sides
7x=14
Divide by 7 to both sides
X=2
First students should be taught to count numbers and make links between the numbers. Then they should learn to identify and create different representation of numbers and learn the concept of zero.
read and write numbers and to count, sort and order them. That way they can compare the size of two sets. And than students should be taught to add and subtract numbers. Adding can be learned by grouping numbers, while subtracting by moving apart given numbers.
Answer:
The slope is -2/3
Step-by-step explanation:
With this its easier to get all of the x's on one side.
distribute the -2/3 to the x and 1. Also add a 2 on each side.
Thats leaves you with y=-2/3x+4/3
You than want to make a chart of x's and y's so you know what this graph looks like
x|y
-3|(10/3)
-2|(8/3)
-1|2
0|(4/3)
1|(2/3)
2|0
3|(-2/3)
To find the slope, it's (y2-y1)/(x2-x1)
So in this case, (0-2)/(2+1)
The slope is (-2/3)
