-4x+3+2x-6
The answer is -2x-3
Answer:
The answer to your question is: x = 32
Step-by-step explanation:
Data
x = ?
It is an equilateral triangle so, the three angles measure the same
2x - 4 = 5y
2x - 5y = 4
The sum of the internal angles in a triangle equals 180°
3(5y) = 180
5y = 180/3
5y = 60
y = 12
2x - 4 = 5y
2x - 4 = 5(12)
2x = 60 + 4
2x = 64
x = 64/2
x = 32
Okay, for variable B you have the data points:
1, 2, 3, 5, 6, 6, 7, 7, 10, and 10.
What you need to do to find the mean (or average) is add all the data up and divide by how many pieces of data you had. So, the sum of all the points is 57. There are 10 points overall.
57/10 is 5.7
Your average for variable B is 5.7
The second matrix system is the correct answer
