Slope is rise over run.
Vertical change/horizontal change
4/3 is the slope
Answer:
=x2y−2xy2+7y2z
Step-by-step explanation:
Simplify
Let's simplify step-by-step.
4x2y+3y2z−2xy2−3x2y+4y2z
=4x2y+3y2z+−2xy2+−3x2y+4y2z
Combine Like Terms:
=4x2y+3y2z+−2xy2+−3x2y+4y2z
=(4x2y+−3x2y)+(−2xy2)+(3y2z+4y2z)
=x2y+−2xy2+7y2z
Answer:
=x2y−2xy2+7y2z
Answer:
1 hour 12 minutes or 1.2 hours
Step-by-step explanation:
You add fractions to get this.
1 room/3 hours + 1 room / 2 hours = 1 room / x
0.33333333+0.5 = 1 room / x
0.83333333 = 1 / x Multiply both sides by x
0.83333333x = 1 Divide by 0.8333333
x = 1/0.833333
x = 1.2 hours or
x = 1 hour and 12 minutes
Answer:

Step-by-step explanation:
For this case we can use the figure attached and we are interested in order to find the value of x.
We have two similar triangles (DEC and ABC) and we can find the scale factor like this:

And now we can apply proportions in order to find the value of x using the two sides DE and BA, since we have the ratio between the triangle DEC and ABC we have this:

And solving for x we got:

And then the distance across the lake would be 2000 ft
