Answer:
a proportional relationship is look at the different values that the variables take on when one variable is one value, and then what is the And then take the ratio between them. and you see y to x, or y divided by x-- the ratio of y to x
If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Writing an Equation to Represent a Proportional Relationship. An expression of equality of ratios is called a proportion. The proportion expressing the equality of the ratios A:B and C:D is written A:B = C:D or A:B::C:D. A is to B as C is to D.
Step-by-step explanation:
A family spent $65 on dinner and left a 20% tip. What was the total cost of their meal?
A. $85
B. $78
C. $67
D. $13
Answer: B, $78
Step-by-step explanation:
If the tip is 20% of the dinner cost, then we have to first find what is 20% of 65.
20% x 65 = 13. So the tip for the dinner is 13 dollars.
Now we have to add it to the original dinner cost.
65 + 13 = 78.
Therefore, the total cost of their meal is 78 dollars. So the answer is B, $78!
Answer: A
Step-by-step explanation:
the total cost of their meal it usally means how much in total so we add 65+20 = 85
OK. these questions are worth ALL my points (55) !

HELP ME PLEASE IT IS DUE TODAY I DON'T UNDERSTAND ANY OF THIS
Answer:
first pic: A and C
second pic: i dont know for A, B = w + 1.4, C = 3y = 5.1, D = z + 1/3 = 1/2
third pic: a. 2x = 14.62 b. there are 2 x's on one side, and 1 number on the other, which can be taken as the answer to 2x. if we can do 2x = 14.62, we can do 14.62 divided by 2 to get the other number x, 14.62 divided by 2 = 7.31. c. i don't know

Step-by-step explanation:
In a laboratory experiment, two mice will be placed in a simple maze with one decision point where a mouse can turn either left (L) or right (R). When the first mouse arrives at the decision point, the direction it chooses is recorded. Then, the process is repeated for the second mouse.
The tree diagram should be drawn where the first stage represents the decision made by the first mouse and the second stage represents the decision made by the second mouse.
Determine all four possible decision outcomes for the two mice.

Consider the division equation "30/5=?". Select the TWO multiplication equations that correspond to the division equation.
Answer:
5x?=30 and ?x5=30
Step-by-step explanation:
First of, these 2 are both the same, and the communitive property applies to both.
The question example is in division, since the communitive prop. doesn't apply on division, it would be almost impossible to find another answer in division form. 5x? Is asking 5 times what equals thirty, so we are using what we know to figure it out. Sorry, I can't provide a good explanation :<
The students in Ms. Douglas’ class worked so hard this year that she has planned a surprise, end-of -year trip for them to a local amusement park. The school principal allows Ms. Douglas to spend a budget of $500 on the trip.
So far she knows :
A coach bus costs $180 to transport them to and from the park.
Price of admission to the park is $15 per person
Part A : Write an inequality that describes that how many students Ms. Douglas can bring on the trip. Define the variable
Part B: Solve the inequality and explain the solution in the context o the problem
Answer:
Part A: 180+15x=500
B: x = 21.333 or 21
Step-by-step explanation:
So in part A since you have 500 to spend and 180 goes to the coach bus, you are left with $ 320 to spend on the students and when you divide 320 by 15, (since the tickets for admission are $15) you end up with 21.333, but since you cant bring .333 of a student on a trip you can bring 21 students, but you can buy 21.333 tickets.
