Answer:
We need to subtract both equations. 2x3+30x-130-2x3+3x+520
that gives
30x-130+3x + 520
33x+390
D is answer
Answer:
D. 33x + 390
Step-by-step explanation:
Profit is the difference between revenue and cost so subtract the given polynomials:
2x³ + 30x – 130 - (2x³ – 3x – 520) = 2x³ + 30x – 130 -2x³+3x+520
combine like terms: 33x +390
Which is equivalent to 3 square root of 8 1/4 x

1:750 scale model of the Sydney Opera House after a trip to Australia. The length of the model is 24.4 centimetrers. Find the actual length x (in meters) of the Sydney Opera House.
Answer:
183 meters
Step-by-step explanation:
A 1:750 scale model means that each cm on the model corresponds to 750 cm of the actual Sydney Opera House. If the model is 24.4 centimeters long, the actual Opera House has a length of:
[tex]x = 24.4*750\\x=18,300\ cm\\x=183\ m[/tex]
The actual length of the Sydney Opera House is 183 m.
a factor of 30 is chosen at random, what is the probability that the number has 2 digits?
Answer:
3/8
Step-by-step explanation:
Let's first start by figuring out all the factors of 30.
They are as follows: 1, 2, 3, 5, 6, 10, 15, 30
30 has 8 factors in total.
3 of the factors have 2 digits.
Probability is number of desired outcomes/number of total outcomes.
We have 3 desired outcomes and 8 total outcomes.
Therefore, the probability that the factor chosen at random will have 2 digits is 3/8.
Factor 12x−54 using the GCF.
Answer:
6(2x-9)
Step-by-step explanation:
The two numbers in question are both even, so we can see that we can pull out 2, giving us:
2(6x -27)
Looking at this, we can see that we can no longer pull out 2, but we can pull out 3, giving us:
6(2x-9)
This can be simplified no further, so this gives us the final answer, where the GCF is 6.

What is the solution to this system of linear equations? x + y = 4 x − y = 6 (4, 6) (6, 4) (5, −1) (−1, 5)
Answer:
x= 4 y = -1
(5,-1)
Step-by-step explanation:
x + y = 4 x − y = 6
Add the two equations together to eliminate y
x + y = 4
x − y = 6
---------------
2x = 10
Divide by 2
2x/2 = 10/2
x = 5
Now find y
x+y = 4
5+y = 4
Subtract 5 from each side
5+y-4 = 4-5
y = -1
Answer
5,-1

Hey so im really confused on how to rewrite problems into radical form, so I was wondering if anyone would be able to show me how to do It step by step?
Answer:
Step-by-step explanation:
Ok so, I'll try to make this explanation super simple for you.
The denominator will always go on the outside and the numerator will be on the inside. Let me give you an example.
Take x^2/3. The answer will be 3√(x^2). Do you see how the 3 is on the outside and the 2 is on the outside?
Take p^4/5. The answer will be 5√(p^4).
I hope this gives you a clear understanding.

What is the measure of the supplementary angle of the 65˚ angle?
A.50˚
B.40˚
C.130˚
D.310˚
Answer:
115
Step-by-step explanation:
When two angles are supplementary, their measures must add up to 180 degrees. Therefore, if we call the other angle x:
x+65=180
x=180-65=115 degrees
Hope this helps!
Answer:
None of them
Step-by-step explanation:
Supplementary angles have 180 degrees
50+65=115
40+65=105
130+65=185
310+65=375

Find any 6 ratinol numbers between -5/6 and 5/8
Answer:
There is a variety of answers. you will find an example below
Step-by-step explanation:
To find the rational numbers between 2 fractions/rational numbers, we have to find the LCM of the denominator, which would increase the value of the numerator. This way you will have more rational numbers between the two.
- 5/6 = -40 / 48
5 / 8 = 30 / 48
Now, we can notice that there is a difference of 70 between the 2. this means you may choose 6 out of these. Here is an example(some of them are simplified)
5/16, 5/8, 7/48 , 1/6 , 2/6, -1/2.
