Answer:
the mean of A and C is 10
Step-by-step explanation:
Given;
mean of A and B = 20
mean of B and C = 24
mean of A, B and C = 18
Recall; A = 40 - B
A = 40 - 34
A = 6
Also, C = 48 - B
C = 48 - 34
C = 14
Therefore, the mean of A and C is calculated as;
B is the correct answer because -3 is the only value x is multiplied by.
Where is the rest at that’s only 1
And x = 6. Which statements are true? Check all that apply. 7x + 4 and 3x + 5 + 4x = 1. When x = 2
