Problem 1
k = Kevin's score
7k = seven times Kevin's score
7k-13 = thirteen fewer than the previous amount = Jason's score of 50
7k-13 = 50
7k = 50+13
7k = 63
k = 63/7
k = 9
<h3>Answer: Kevin scored 9 points</h3>
================================================
Problem 2
p = number of goals Paul scored
6p = six times the previous unknown number
6p-8 = eight fewer than the previous number = Ken's goal count (22)
6p-8 = 22
6p = 22+8
6p = 30
p = 30/6
p = 5
<h3>Answer: Paul scored 5 goals</h3>
Answer:
X=60°
Y=50°
Step-by-step explanation:
Triangles must equal 180° when you add all angles together.
<u>Triangle</u><u> </u><u>with</u><u> </u><u>angle</u><u> </u><u>X</u>
To find the value of Y takes a few more steps, but it isn't hard!
Angle Y is on a line, which equals 180° just like a triangle.
We know X=60°, but we don't know what the blank angle equals.
We use the same steps as we did when finding X
- 60+50=110
- 180-110=70
- Blank angle=70°
We know that the blank angle=70° and that X=60°
Since the line equals 180, we add the two angles and then subtract from 180, just like before!
- 70+60=130
- 180-130=50
- Y=50°
