Answer:
147
Step-by-step explanation:
x = 7,
3x² = 3 × 7²
= 3 × 49
= 147
The answer to the expression is -97/20 or -4.85
Answer: 
Step-by-step explanation:
When we throw a die , Total outcomes =6
When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]
Given : Three fair dice are rolled, one red, one green and one blue.
Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed
By Permutations , the number of favorable outcomes = 
The probability that the upturned faces of the three dice are all of different numbers = 

The probability that the upturned faces of the three dice are all of different numbers is
.
6y-5=11
Move -5 to the other side. Sign changes from -5 to +5.
6y-5+5=11+5
6y=11+5
6y=16
Divide by 6 for both sides to get y by itself.
6y/6=16/6
Cross out 6 and 6, divide by 6 and then becomes 1*1*y=y
y=16/6
Reduce 16/6 by dividing by 2
16/2=8
6/2=3
Answer: y=8/3 or y=2 2/3
