Hope this is what you need
Answer:
I am not sure of the equation but I interpreted it as x^2a^2+3xa^2+2a^2
Step-by-step explanation:
X^2a^2+3xa^2+2a^2
1. a^2 (x^2+3x+2)
2.a^2(x^2+2x+x+2)
3. a^2(x(x+2)+x+2)
4. a^2(x+2)(x+1)

Or if you must,
2.4 rounded down is 2.
12 divided by 2 is 6 so the answer would be less than but not greater than 6.
Final answer:
The estimation of 2.436 divided by 12 is approximately 0.203 .
Explanation:
The student wants to estimate the result of 2.436 divided by 12. The number 2.436 is closer to 2, therefore we can estimate it as 2. Now our division problem becomes 2.436 divided by 12. It would be less than 1 since 2 is smaller than 12. However, to get a more exact estimation, we could think of it as if every 1 of the 12 gets 1/6 of the 2, which means each one would get about 0.203. Therefore, 2 divided by 12 is approximately 0.203.

y=mx+b, m=slope
slope=(y1-y2)/(x1-x2)
we have points
(4,5)
(-3,-1)
(x,y)
x1=4
y1=5
x2=-3
y2=-1
subsitute
(5-(-1))/(4-(-3))=(5+1)/(4+3)=6/7
y=6/7+b
sybsitute and solve for b
(4,5)
x=4
y=5
5=6/7(4)+b
5=24/7+b
5=35/7
subtract 24/7 from both sides
11/7=b
y=6/7x+11/7
convert to the point slope form and find equivilent fraction
since the question asks for 2 answers that are correct and only 2 of the equations have slope of 6/7 I can guess that the answers are B and C
y -y1 = m(x - x1)
First, we need to calculate the slope.
The slope is 6/7
Next, we plug in both points.
m = 6/7, (x1,y1) = (4,5)
The equation will be:
y - 5 = 6/7 (x - 4)
Plugging in m = 6/7, and (x1,y1) = (-3,-1)
The equation will be
y + 1 = 6/7 (x + 3)
Your answer is B and C.
In June, Riley finished 40% of the questions in her packet.
How many more questions had Riley finished than Annabel?
Answers
Riley finished 18 more questions than Annabel, as per the given condition.
Given that,
Annabel and Riley were given a homework packet of 120 math questions to finish over the summer. Annabel finished 25% of the questions in her packet. In June, Riley finished 40% of the questions in her packet.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Question finished by Annabel = 25% of 120 = 0.25 × 120 = 30
Question finished by Riley= 40% of 120 = 0.40× 120 = 48
Difference in the question = 48 - 30 = 18
Thus, Riley finished 18 more questions than Annabel, as per the given condition.

3x - 5y =8
Can you help me do this in the simplest way please? I'm kinda struggling to get this concept down... :(
Answers
So, it doesn't matter where you start. I would start finding the x in the first equation, like this:
x - 2y = 5
x = 5 - 2y
Which is really easy, isn't it?
Now you know that x is equal to 5 - 2y, so you can substitute the x in the second equation. (You could have done the same solving by y, it doesn't matter :D )
3 ( 5 - 2y ) - 5y = 8
15 - 6y - 5y = 8
- 6y - 5y = 8 - 15
-11y = -7
y = -7/-11 = 7/11
Now you found your y! Let's substitute it in the first equation. (The beginner one, not the one that you worked on)
x - 2 (7/11) = 5
x - 14/11 = 5
x = 5 + 14/11
x = 69/11
I know you got it now! ;) Otherwise ask me whatever you want!
