x = 7
3*x-6-(15)=0
3x - 21 = 3 • (x - 7)
Solve : 3 = 0
Solve : x-7 = 0
Add 7 to both sides of the equation :
x = 7

Answer:
Step-by-step explanation:
To calculate the weighted moving average for period 13 with weights 0.4 and 0.3.
P13 = (30.7x 0.4) + (42.0x 0.3)
P13 = 12.28 + 12.60
P13 = 24.88
Add the fractions together to find the portion who like basketball, soccer and football.
=1/3 + 1/8 + 5/12
need a common denominator (24)
=8/24 + 3/24 + 10/24
=21/24
simplify by 3
=7/8 like basketball, football & soccer
7/8 is the total for basketball, soccer and football. If 8/8 represents the whole class, then subtract 7/8 from 8/8 to find the number who like baseball.
=8/8 - 7/8
=1/8 of the remainder likes baseball
ANSWER: 1/8 of the students like baseball
