Answer: Marble
Step-by-step explanation:
Multiply 3x4x6 and you should get 72. Divide 184.32 by 72 and you should get 2.56 which is marble.
Answer:
y = - 2x + 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (5, 3) and (x₂, y₂ ) = (4, 5)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 5), then
5 = - 8 + c ⇒ c = 5 + 8 = 13
y = - 2x + 13 ← equation of line
15/50 * 2/2 = 30/100
Now you can easily see decimal and percent form
Decimal: 0.30
Percent: 30 percent
