The answer is C
the mean is the average which is solved by adding up all of the numbers and then dividing that by how many numbers there are, 45/5 = 9
Initially Kevin had 25
Step-by-step explanation:
Given that,
James have 20 more than Kevin
J = K + 20
If Kevin loose 10 then james will have 3 time Kevin
J = 3( K - 10)
Equate both the equation,
3(K-10) = K+20
3k - 30 = k +20
3k - k = 20 + 30
2k = 50
K = 25
So initially Kevin had 25

Step-by-step explanation:
Answer:9.0875
Step-by-step explanation:
[2.4–(0.3–3.21)÷2+0.44÷(−2)]÷ 2/5=
[4.8:2-(-2.91):2-0.44:2]:2/5=
=[(4.8+2.91-0.44):2]*5/2=
=[(7.71-0.44):2]*5/2=
=(7.27:2)*5/2=(7.27*5):(2*2)=
=36.35:4=9.0875
