Answer:
-3.5g - 4
Step-by-step explanation:
First, you would organize the equation by placing them into groups that can be combined. This would leave you with the equation: -3g -3g +2.5g -7 +3. Then you would combine like terms by adding -3g, -3g, and 2.5g which would result in -3.5g and adding -7 and 3 which would result in -4. Smush the equation back together to get the end answer of -3.5g - 4.

The width of a circular track is 2 meters. If the radius of the outer circle is 6 meters, find the area of the track.
Answer:
[tex] 62.8 \: {m}^{2} [/tex]
Step-by-step explanation:
Radius of outer circle = 6 m
Width of the track = 2 m
So, radius of inner circle = 6 - 2 = 4 m
Area of the track = Area of outer circle - Area of inner circle
[tex] = \pi {6}^{2} - \pi {4}^{2} \\ \\ = \pi( {6}^{2} - {4}^{2} ) \\ \\ = 3.14 \times (36 - 16) \\ \\ = 3.14 \times 20 \\ \\ = 62.8 \: {m}^{2} [/tex]
Is {(-3,2), (2.2), (12)(-3,1),(0,3)} a function?
Answer:
No
Step-by-step explanation:
Because there are two inputs (-3) and they both lead to two different outputs (2 and 1), it isn't a function

[Easy Question] Answer this with evidence of the answer that you provided with me!
Answer:
48
To start you will find the area as if it was a rectangle. To do that you have to do 8x12. 8x12 = 96, but to find the area of a triangle you take the area of the rectangle and divide it by 2. 96 divided by 2 is equal to 48.
There are other methods of solving this but I think this is the easiest way!

12 and 8
Step-by-step explanation:
which images shows a reflection
I'll Give You Some Hints:
Let's Look at C.
In C, the triangle is translated 2 units to the right. Which means that it cannot be a reflection.
Let's Look at B.
In B there is a sideways triangle. That means it's a Rotation. Which means it's not Reflected.
Lastly, Let's Look at A.
To get from the original triangle to the triangle in A, you have to reflect twice. Once along a vertical line, and then along a horizontal line.

5v^2 -- 30v + 40
Factoring polynomials
First let's factor a 5 from every term.
5v^2-30v+40
=5(v^2-6v+8)
The v^2-6x+8 can be further factored using the x method(as I call it, its not its official name of course), You can get
5(v^2-6v+8)
=5(v-2)(v-4)
Done! any questions just ask in the comment section.
**Edit: You needed the area model so here is how it goes, I cannot draw lines but I will try my best.
we have original equation 5v^2-30v+40
first simplify to 5(v^2-6v+8)
Now factor the second part but using area model.
v -2
_____________
v | [tex]v^2[/tex] | -2v |
--------------------------
-4 | -4v | 8 |
_____________
This is basically the area model the thing in the middle is suppose to be a rectangle split into 4 parts and then the numbers on top and left are suppose to be the factored equations while they multiplies to the number in the box.
Is this efficient?
Definitely not, it took me longer to draw the box than write my whole first explanation.
Is this easy?
No, again it took me about 170 times longer to think of this answer this way.
Should you use this method?
Sure if your teacher wants you to, but just saying later in algebra these methods are way to slow and there are way better methods to factor, so if you arn't solid in the area model just don't worry about it.

Answer: 0.25g<2.50.... g<10
Step-by-step explanation: Let us say that the number of gumballs bought is represented by the variable g. In this case, the question is asking how many gumballs can be bought without surpassing the price of $2.50. We know that each gumball is $0.25, therefore the number of gumballs we buy times $0.25 has to be less than $2.50. Hence, the inequality would be 0.25g<2.50. If we were to solve this then g<2.50/0.25-----> g<10. In conclusion, the number of gumballs you can buy has to be less than 10. Thank you!

a framer sells 16 pounds or his small 48 pound potato crops what percent does he sell
Answer:
Is it 32
Step-by-step explanation:
I think your suppose to subtract if you get it wrong i'm sorry
Answer:
33.3333333% (with the 3 repeating forever)
Step-by-step explanation:
If they sell 16 pounds/48 pounds, you can first simplify this fraction:
16/48 = 1/3.
Then, you do 1 divided by 3 and you would get 0.33333...
As a percent, this is 33.3% (where the 3 is repeating forever)
