Answer:
19 points
Step-by-step explanation:
Given that :
Fabio had 7 points less than 2 times as many points as Carlos
Let Fabio's point = f
Carlos point = c
Equation relating the number of points scored by both players.
Points scored by Fabio = 31
f = 2c - 7
Carlos point = c
31 = 2c - 7
31 + 7 = 2c
38 = 2c
c = 38/2
c = 19
Hence, Carlos's points is 19
Answer: -94
Step-by-step explanation:
Mean = 72
First round = 72-3 = 69
Second round = 72-1 = 71
Third round = 76
Explanation:
Total score = 72*3 = 216
69+71+x = 216
140+x = 216
x = 76
Sec is also known as 1/cos.
Use the calculator to find 1/cos19
Distance = sqrt (13-18)^2 + (20-8)^2 )
= sqrt ( 5^2 + 12^2)
= sqrt 169 = 13
