Answer:
4 out of 20 if I'm not mistaken
Step-by-step explanation:
Add all the numbers and then you get 20 and there are 4 yellow marbles so 4 out of 20
Well, the easiest way to go about this is to take out the number of games played (temporarily, we'll need that number later.)
We'll make y the points per game and x the number of games.
Now the way to find this out is to divide the number of points by the number of games so:
y = 64/x
now we know x is 8 so we need to solve for y
y = 64/8
y = 8
Teri scored 8 points per game.
Answer:
-8
Step-by-step explanation:
Both the numbers are negative so you add them together and keep the negative sign
Answer:

The graph is attached.
Step-by-step explanation:
Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.
You know that you want to to have at most 25 samples, then:

And you want to have at least 3 times as many sedimentary samples as
metamorphic samples, then:

Therefore, the system of inequalities that model the situation is:

The y-intercept of the line
is:

And the x-intercept is:

Knowing this, you can graph the line
The y-intercept of the line
is:

And the x-intercept is:

Knowing this, you can graph the line.
Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.
Answer:
<h2><em> -12y² + 72y</em></h2>
Step-by-step explanation:
Use the distributive property: <em>a(b + c) = ab + ac</em>
<em>-12y(y - 6) = (-12y)(y) + (-12y)(-6) = -12y² + 72y</em>
