Answer:
I have attached a picture of the completed graph.
The equation is k = r + 7
Kyle will be 59 when Ryan is 52.
Explanation:
Kyle's age is always seven years higher than Ryan's age.
Therefore, k (Kyle's age) = r (Ryan's age) + 7 (Number of years different)
Answer:
Step-by-step explanation:
Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)
Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)
Since the angles in a triangle add up to 180 degrees ,
Remove brackets:
Add/Subtract:
Subtract 213 from both sides:
Divide both sides by -3:
Answer:
11.
Take out 2x ( greatest common factor )
Factor
Don't forget about the 2x we took out earlier
Solution to 11:
12.
This is the difference of squares, so let's use the formula...
if, and
then, the Solution to 12 is:
13.
First of all, you must find the greatest common factor because there isn't anything else you can do.
Now you can see the difference of cubes...
so, the Solution to 13 is:
