An unknown number y is 10 more than an unknown number x. The number y is also x less than 3. The equations to find x and y are shown below. y = x + 10 y = −x + 3 Which of the following statements is a correct step to find x and y? (4 points) a Add the equations to eliminate x. b Multiply the equations to eliminate y. c Write the points where the graphs of the equations intersect the x-axis. d Write the points where the graphs of the equations intersect the y-axis.
Answer:
Answer (a)
Step-by-step explanation:
y = x + 10
y = −x + 3 It's easier to see what to do next if you first write these equations in a column.
Combining these equations, we get 2y = 13, so that y = 13/2.
Answer (a) is the best choice of the four possible answers.

Dina has a number cube that she uses for a game.
The number cube has the shape of a triangular pyramid, with 4 faces numbered 1 through 4. Dina rolls the number cube 100 times and records the results. She calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.23 0.24 0.26 0.27
Which statements about Dina's experiment are true?
Select each correct answer.
The relative frequencies in the table are reasonably close.
The theoretical probability of rolling an even number is 0.51.
The relative frequency of rolling an even number is 0.51.
The number cube is not likely to be fair.
Answer: the relative frequencies in the table are reasonably close.
Step-by-step explanation:
Theoretically relative frequency for all numbers are 0.25. If cube is cast
100 times there my be small fluctuations.

Which expression represents the phrase below?
3 fewer than a number, p
6th grade math please help
Answer: 9x-3x and 5x+x
Step-by-step explanation:
1. Brianna's thinking is incorrect because of course, when x is 0, the expression will equal whatever value isn't an x term. To find equivalent expression, you actually need to find which expressions have the same amount of x terms and the same value.
2. Expressions A and C are equivalent.
3. Expression A can be simplified, as you can do 9x - 3x = 6x, so your final expression would be 6x - 4. Expression C can also be simplified with 5x + x = 6x, which can then also be written as 6x - 4. This means both expressions have the same amount of x terms, and the same value, so they are equivalent.
Answer:
Below
Step-by-step explanation:
Brianna's teacher asks her which of these three expressions are equivalent to each other
Expression A: 9x−3x−4 Expression B: 12x−4 Expression C: 5x+x−4
Brianna says that all three expressions are equivalent because the value of each one is −4 when x=0.
Brianna's thinking is incorrect. Identify the error in Brianna's thinking. Determine which of the three expressions are equivalent. Explain or show your process in determining which expressions are equivalent. Enter your answers and your explanation or process in the space provided.
So let's just simplify A and C. B is already simplified.
9x-3x-4
6x-4
5x+x-4
6x-4
So yes, Brianna is incorrect. She added 3x and 9x, instead of subtracting 3x from 9x. A and C are equivalent, but B is all alone.

Dylan started with 30 baseball cards and gave away x cards. Sebastian started with 40 cards and gave away twice as many cards as Dylan did.
How many cards did Dylan give away if they had the same number if cards left?
A: 20

C: 5
D: 15
Answer:
he gave away 5 because if sebastian gave twice as many away and ended up with the same as dylan then it must be 5

A new store is handing out small gifts to the customers who come in. Elizabeth is handing out pens of various colors.She has determined that the chance of a customer receiving a blue pen is 0.008. Ricardo is handing out tote bags of various colors. He has determined that the chance of a customer receiving a blue tote bag is 0.04. What statement describes the likelihood of a customer getting a blue tote bag or a blue pen?
It is very unlikely that a customer gets a blue tote bag, but it is very likely that a customer gets a blue pen.
It is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen.
It is very likely that a customer gets a blue tote bag, but it is very unlikely that a customer gets a blue pen.
It is very likely that a customer gets a blue tote bag, and it is very likely that a customer gets a blue pen.
Help if you are sure!
DONT send links
Answer:
99% sure it's B !!!
Step-by-step explanation:
the likelyhood of getting a blue pen is microscopic, not even a 1% chance and the likelihood of getting a blue tote bag is also pretty small
It is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B)
How can we interpret probability?Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.
Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).
Since it is given that:
The chance of a customer receiving a blue pen = 0.008The chance of a customer receiving a blue tote bag = 0.04Both probabilities are too close to 0, than 1. So they both are very unlikely to occur.
Thus, it is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B).

Answer:
The area of the shaded region is 24 cm^2.
Step-by-step explanation:
1. find the area of the rectangle
A = 8*4
A = 32 cm^2
2. find the area of the triangle
A = (4*4)/2
A = 8 cm^2
3. to find the area of the shaded region, subtract the area of the triangle from the area of the rectangle
A = 32 - 8
A = 24 cm^2
Answer: the area of the shaded region is 24 cm^2.
Answer:
