Answer:
x = 6
Step-by-step explanation:
12x+252=324
Subtract 252 from each side
12x+252-252=324-252
12x =72
Divide each side by 12
12x/12 = 72/12
x =6
Answer:the third option is the correct answer
Step-by-step explanation:
The given system of linear equations is expressed as
y – 3x = –2 - - - - - - - - - - - -1
y = 4 - - - - - - - - - - - - - 2
The first step is to substitute equation 1 into equation 2. It becomes
4 – 3x = –2
Subtracting 4 from the left hand side and the right hand side of the equation, it becomes
4 - 4 - 3x = –2 - 4
- 3x = - 6
Dividing the left hand side and the right hand side of the equation by - 3, it becomes
- 3x/ - 3 = - 6/ - 3
x = 2
(2, 4)
Answer:
x = 15
Step-by-step explanation:
Given
2 = -
+
x
Multiply through by 4 to clear the fractions
8 = - 7 + x ( add 7 to both sides )
15 = x
There would be 84 winning rows of 6 in a row.
On each face of a cube, there would be 6 vertical rows, 6 horizontal rows and 2 diagonal rows. That is a total of 14 rows per face.
A cube has 6 faces.
6 x 14 = 84
