C. 52
Work:
(5x - 22) + (4x + 4) = 90
9x - 18 = 90
9x = 108
x = 12
4(12) + 4 =
48 + 4 = 52
Thwre are 28 clients who don not play any of the instrument using the principle of Venn distribution.
<u>Using a Venn diagram analogy</u> :
- Total number of client, U = 108
- Piano, P = 42
- Guitar, G = 51
- Piano and Guitar, (PnG) = 13
- None =?
<u>From the information given</u> :
- P only = 42 - 13 = 29
- G only = 51 - 13 = 38
<u>The total number of clients can be related thus</u> :
- Total = P only + G only + PnG + None
108 = 29 + 38 + 13 + None
108 = 80 + None
None = 108 - 80
None = 28
Therefore, the number of clients who do not play any of the instruments is 28

Step-by-step explanation:
Answer:
QV = 36 UNITS
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1.
QU is the median and V is Centroid. Therefore,
QV : VU = 2 : 1
Let QV = 2x & VU = x
QV + VU = QU
2x + x = 54
3x = 54
x = 54/3
x = 18
QV = 2x = 2*18 = 36
