Teah was selling candy bars for a fundraiser. She spent $25 on a box of candy bars and sold each candy bar for $2.50. Her profit was $75. Teah wrote the equation 2.5c−25=75 for this situation, and she found c=40. Which statement is true about the solution c=40?

Answers

Answer 1

Answer:

The equation is not true. It is actually c=30

Step-by-step explanation:

First you have to divide amount of money she's selling the candy bars for which is $2.50.

If her profit was $75, you want to know how much bars she sold, you will have to divide the amount of money she's selling the candy bars for and the amount she's earning which is $75 divided by $2.50 which is 30.

So c= 30

The table below shows the price, in dollars, for the number of Rose's indicated. ​

Answers

Answer:

1. The relationship is proportional.

2. The cost for 30 roses is 90 dollars.

Step-by-step explanation:

1. The price (y) divided by the number of roses (x) equals 3, no matter what section in the table you try it on; y/x = 3. This means that the relationship is proportional.

Another way to explain this is x * 3 = y. For example, 3 roses * $3 = $9

2. We know that one rose costs $3. So you can multiply:

30 roses * $3 = $90

Answers

Answer:

no solution

Step-by-step explanation:

start by

distributing the 2 on the right side of the equation

you should get 4n-9=10+4n

then you should try to combine like terms, start by subtracting the 4n on the left side from the one on the right

both of those should cancel out

leaving you with -9=10, which is obviously false, meaning there is no solution

Answers

Answer:

x = 1.5

Step-by-step explanation:

First, we distribute (get rid of parentheses):

6x - 3 - 3x = 5 - x - 2

Then, we simplify:

3x - 3 = 3 - x

Then, we combine like terms:

3x + x = 3 + 3

Then, we simplify again:

4x + 6

Finally, we divide 4 on both sides:

We got x = 1.5

If R is the midpoint of QS, QR = 8x – 51 and RS = 3x – 6, find QS.

Answers

Answer:

42 units

Step-by-step explanation:

If R is the midpoint of QS, then by definition, QR = RS. Since QR = 8x - 51 and RS = 3x - 6, set these equal to solve for x:

QR = RS

8x - 51 = 3x - 6

5x = 45

x = 9

Now that we know x = 9, we can plug this back into one of the expressions for QR or RS to find its length:

QR = 8x - 51 = 8 * 9 - 51 = 72 - 51 = 21

Since half of QS is 21, then the whole of QS is twice that:

2 * 21 = 42

The answer is thus 42 units.

HAS TO BE DONE BY TOMORROW - A positive integer is called snakelike if its digits alternately increase and decrease or vice versa. For example, 130 and 91727 are snakelike. However 123 is not snakelike (2 is greater than 1 but not 3) and 91727 is not snakelike (7 is greater than 1 but not 7)

A) How many 4-digit snakelike numbers contain each of the digit 1,2,3,4 exactly once


B) How many 3-Digit snakelike numbers have 6 as their middle digit


C) a 7-digit snakelike number starts with digit 9. Explain why it last digit cannot be 0

Answers

Answer:

  A) 10

  B) 39

  C) the last digit must be greater than the previous digit. 0 is not greater than any other digit, so the last digit cannot be 0.

Step-by-step explanation:

A) Numbers of the form low, high, ... can start with digits 1 or 2, and the 3rd digit will be the other one. There 4 such numbers 1423, 1324, 2413, 2314. In addition, For a first digit of 2, the second digit may be 1, allowing 2143. Thus, there are 5 numbers starting with 1 or 2 and ending with 3 or 4.

There are 5 additional numbers that are the reverse of these.

  There are 10 4-digit snake-like numbers containing 1–4 exactly once.

__

B) We assume a "3-digit number" will be in the range 100–999. That is, the leading digit will not be zero. If you allow a leading 0, the answer is different.

With 6 as a middle digit, the numbers 1–5 can be the first digit and the numbers 0–5 can be the last digit. Hence there are 5·6 = 30 numbers of the form low-6-low.

If the form is high-6-high, there are 3 possible first digits and 3 possible last digits, so 3·3 = 9 numbers of the form high-6-high.

  There are 39 3-digit snake-like numbers with 6 as the middle digit.

__

C) A 7-digit snake-like number will alternate high-low, with high being the last digit. Hence the last digit must be higher than the previous digit, so cannot be 0.
