Given
--- The variation
Required
Determine the constant of proportionality (k)
Express as an equation
Multiply both sides by 
Make k the subject
Given that:
We have:
This can be represented as:
Answer: 15
Step-by-step explanation:
Average is sum of scores/ number of scores, from the question, average is given as 15.
Let the missing score be x
Equation for the questionis represented as: 12 + 18 + x /3 = 15
30 + x /3 = 15
Cross multiply
30 + x = 15×3
30 + x = 45
Subtract 30 from both sides
30 + x -30 = 45 -30
x = 15.
Check:
12 + 18 + 15/3 = 15
45/3 = 15
I hope this is clear, please mark as brainliest answer
Answer:
idk sorry
just tryn to get points
Step-by-step explanation:
Total awpaws and guavas sold in a week = 328
Let the number of pawpas and guavas be x
ATQ
3x + 5x = 328
8x = 328
x = 328/8
x = 41
Pawapas in a week = 123
Guavas in a week = 205
