Answer:
1/2 of a pie.
Step-by-step explanation:
There are 4 people (Emilio and his 3 friends).
If he splits 2 pies to 4 people, our equation is 2/4.
Simplify to 1/2.
Answer:
4.5 hours
Step-by-step explanation:
let t be the time elapsed
Therefore, we can set up a system of equations and solve accordingly
2t + 16.5 = 4t + 7.5
2t = 9
t = 4.5 hours more till they paint the same amount in square feet
How to Draw Parallel Lines:
1. Draw a straight line any length
2. Draw another straight line any length
(note : ensure the lines will never intersect)
They shall never horizontally or vertically.
How to Draw Perpendicular Lines:
1. Draw a straight line vertically
2. Draw a straight line horizontally
(note : length does not necessarily matter)
The two lines must cross at right angles to each other!!
With the parallel line instructions, simply just draw lines but, when given the slopes of two lines, you must get graphing paper or make your own, and graph it by plotting points and then getting a ruler and tracing it.
With the perpendicular lines it helps with showing a relation between situations along with given slopes. They shall intersect always and meet at a 90° angle. Use the equations and plot them then take a ruler and trace them and notice the intersection. Solve it yourself and see that the intersection and the answers you got are the same.
Answer:

Step-by-step explanation:
The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.
Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.

So the missing angle is 109°. Now we can find the value of x.
We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.

Now we know x is 71
Hopefully this will help you out.
