membership = 20
book cost = 3 x number of books
t = 20 + 3b
Answer:
The answer would be 3b + 20 = t
Step-by-step explanation:
I think the question is referring to the total cost per month to be a member.
Since it costs 20$ monthly no matter what, that price will always stay the same per month.
However, it also costs $3 per book purchased. This price may not always stay the same, because you could buy a different number of books each month, and the price would be different. The cost for books depends on the number of books you buy, which is not stated in the question.
That is why you replace the number of books with a variable, in this case b.
So the equation would be 3b + 20 = t , with 3 being the cost per book, b being the number of books, 20 being the monthly cost, and t being the total amount per month.

Answer:
(-1, 1)
Step-by-step explanation:
Multiply f(x) or y value by -2, so (-1, 2) -> (-1, -4)
Add 5 to the f(x) or y value since it is a vertical translation, so (-1, -4) -> (-1, 1)

Answer:
4 times, he bought dinner 4 times
Step-by-step explanation:
if kevin get paid for 3 hours, then you would multiply $14 by 3. you would end up with $42, then the weekly allowance is $21. then by adding $21 to the $42 we have you would get $63. then a bus ride costs $2.50 and since he rode it 6 times you would multiply $2.50 by 6, which would equal $15. Then subtracting $15 from the $63, you would end up with $48, and then by dividing the total amount for the dinner each time bought, so $12/$48 would equal to 4 times.

Answers
Answer:
x = -10
Step-by-step explanation:
2(x+3) = x-4 --> multiply (x+2) times 2
2x+6 = x - 4 --> subtract x from both sides
x+6 = -4 --> subtract 6 from both sides
x = -10
Answer:
x = -10
Step-by-step explanation:
Simplify both sides of the equation.
2 (x+3) = x − 4
(2) (x) + (2) (3) = x + −4 (Distribute)
2x + 6 = x + − 4
2x + 6 = x − 4
Subtract x (1x) from both sides
2x + 6 − x = x − 4 − x
x + 6 = − 4
Subtract 6 from both sides
x + 6 − 6 = − 4 − 6
x = -10

Step 5 of 5: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
Answers
Answer:
Step-by-step explanation:
The mean of the data is 31 hours and the median of the data 27.2 hours.
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
Step 1:
The median is a value that divides the whole data into two equal parts. It implies that the median represents the 50th percentile of the data.
Given that the median is 27.2 hours, thus the 54th percentile should be greater than 27.2 hours.
Thus, the given statement is false.
Step 2:
Let assume that N is the total number of families
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
It means that 7% of N = 24
N = 24/0.07
N = 343
Step 3:
From (2), N = 343
Given that median= 27.2 hours.
It means 200 families turned on their television for less than 27.2 hours.
We don't know if this is true for 35 hours. 100 families may use less than 35 hours and 200 may use more than 35 or vice versa. In addition to that, even 50 families might use less than 35 and 350 may use more than 35 hours.
Hence, the statement is false.
Step 4:
The median is the 50th percentile value which is = 27.2 hours
Step 5:
The statement is false
The 25th percentile is the first quarter of the data and if the 7th percentile is 16 hours, then the 25th percentile should be greater than that.

Steve already has 5 flowers in his garden, and he can also grow 1 flower with every seed packet he uses. Write an equation that shows the relationship between the number of seed packets x and the total number of flowers y.
Answers
Answer:
y = x + 5
Step-by-step explanation:
Using the information provided we can create the following equation. Since every seed packet can grow 1 single flower we would need to multiply 1 by the number of seed packets (x), which simplified would be just x . Next we are told that Steve already has 5 flowers in his possession meaning we need to add this to the new flowers that he is growing to get the total number of flowers.
y = x + 5
