Mean of a data = Sum of all observations ÷ Total number of observations

Mean of this data will be :

Sum of all observarions = 17 + 13 + 18 + 20 + 17 + 15 + 12 = 112

Total number of observations = 7

Mean = 112 ÷ 7

Mean = 16

(a) Simplify the expression: (4x - 6) - (x + 5)
Liono4ka [1.6K]

Answer:

a) 3x - 11

b) 10x + 4

Step-by-step explanation:

a) The negative sign before the (x+5) means to subtract those values. Reverse the signs. Then combine like terms:

4x –6 –x –5. 4x–x–6–5

3x –11

b) Put all the x terms together.

Put all the integers together.

Add. Adding a negative is the same as subtracting.

4x+x+5x = 10x

+6-2 = 4

Combine them:

10x + 4
