Answer:
C) Distributive Property
Step-by-step explanation:
You're <em>distributing</em> in the 3 when you multiply it by the 5 and the 2 in the algebraic process:
➦ ➦
3•(5 + 2) = (3 • 5) + (3 • 2)
So, the 3 was <em>distributed</em> between the 5 and 2 when you multiplied.
Hence, this is the distributive property.
Answer:
x < - 7
Step-by-step explanation:
Given
3(x - 2) > 5x + 8 ← distribute parenthesis on left side
3x - 6 > 5x + 8 ( subtract 3x from both sides )
- 6 > 2x + 8 ( subtract 8 from both sides )
- 14 > 2x ( divide both sides by 2 )
- 7 > x, hence
x < - 7
x+142 =3x+64
subtract x from each side
142 = 2x+64
subtract 64 from each side
142-64 = 2x
78=2x
divide by 2
78/2 = x
x=39
The number is 39
