<h3><u>
Answer:</u></h3>
Option: C is the correct answer.
$ 1.50 is the cost of 1 eraser.
<h3><u>
Step-by-step explanation:</u></h3>
Alicia bought a notebook and several erasers at the student store.
Let the cost of 1 eraser=$ x.
Now from the scatter plot we could see that when Alicia did not bought any eraser then her total cost =$ 2.
That means cost of a notebook=$ 2.
Now when she buys a notebook and two eraser then she pays=$ 5.
i.e.
Total cost=cost of notebook+ 2× cost of 1 eraser
Total cost=cost of notebook+2×x
i.e.
5=2+2x
⇒ 2x=5-2
⇒ 2x=3
⇒ x=1.5
Hence, cost of one eraser is:
$ 1.50
-84 > -6(2 - 3b)
<em><u>Distributive property.</u></em>
-84 > -12 + 18b
<em><u>Add 12 to both sides.</u></em>
-72 > 18b
<em><u>Divide both sides by 18.</u></em>
-4 > b
The value of b is less than -4
Answer: 4 terms
Step-by-step explanation:
-4a , 8c, -4b, and 3
You can express the edge lengths in terms of "cubes" or you divide the total volume by the volume of a cube. It works either way.
Edge lengths are
.. 80 cubes by 8 cutes by 13 cubes
so total volume is
.. (80 * 8 * 13) = 8320 cubes
In cubic inches, the volume is
.. (20 in)*(2 in)*(3 1/4 in) = 130 in^3.
The volume of a 1/4-in cube is (1/4 in)^3 = 1/64 in^3.
Then the number of cubes that will fit in the prism is
.. (130 in^3)/(1/64 in^3) = 8320 . . . . cubes
8320 cubes are needed to fill the rectangular prism.
