<span>3/5 of 215
Whenever you see the word "of" in a word problem, automatically think "multiplication".
3/5 </span>× 215
0.6 × 215
129
So, 3/5 of 215 is 129.
Answer:
Equations are inconsistent.
Step-by-step explanation:
Given : x + y = 6
y = 3 - x.
To find : Identify the type of system.
Solution : We have given that
x + y = 6 →→→→→→→( equation 1).
y = 3 - x →→→→→→→( equation 2).
Plugging the values of y = 3 - x from equation (2) in equation (1).
x + (3 - x ) = 6
x + 3 - x = 6.
3 = 6
It has no solution , these lines are parallel.
Therefore, Equations are inconsistent.
Answer:
2n+2 ways to win
Step-by-step explanation:
You generalize by observing patterns in the way you solve the smaller problems.
The number of winning moves is 2n+2: the total of the number of diagonals, columns, and rows.
For an n×n board, there are 2 full-length diagonals, n columns, and n rows, hence 2+n+n = 2n+2 ways to win.
