Sara ​says, "If you subtract 15 from my number and multiply the difference by negative 4​, the result is negative 48​." What is Sara's number?

Answers

Answer 1

Answer:

I'm not 100% sure but I believe the answer is 27

because -48/-4=12

12+15=27

Answer 2

Answer:

Write the equation and go backwards.

N - 15 x -4 = -48

Instead of multiply divide and add instead of subtract

-48/-4=12

12+15=27

check if 27 is correct. 27-15=12 x -4 = -48

27 is your number. Hope this helps

Yesterday, the price of a gallon of gas at five gas stations was $3.72, $3.87, $3.78, $4.09, and $3.989, respectively, but today each gas station raised its price by $0.08. What is today's mean price of a gallon of gas at the five stations?

A. 3.97
B. 4.05
C. 3.89
D. 3.81

Answers

Answer:

Option (A) 3.97.

Step-by-step explanation:

Price for one gallon of gas in gas station 1 = $3.72 (Yesterday)

Price for one gallon of gas in gas station 2 = $3.87 (Yesterday)

Price for one gallon of gas in gas station 3 = $3.78 (Yesterday)

Price for one gallon of gas in gas station 4 = $4.09 (Yesterday)

Price for one gallon of gas in gas station 5 = $3.989 (Yesterday)

Prise raised by each gas station Today = $0.08

Price for one gallon of gas in gas station 1 = $3.72 + $0.08

                                                                      =  $3.80 (Today)

Price for one gallon of gas in gas station 2 = $3.87 + $0.08

                                                                       =  $3.95 (Today)

Price for one gallon of gas in gas station 3 = $3.78 + $0.08

                                                                       =  $3.86 (Today)

Price for one gallon of gas in gas station 4 = $4.09 + $0.08

                                                                       =  $4.17 (Today)

Price for one gallon of gas in gas station 5 = $3.989 + $0.08

                                                                       =  $4.069 (Today)

Mean = Sum of the Terms Number of Terms / Total Number of Terms

          = $3.80 + $3.95 + $3.86 + $4.17 + $4.069 / 5

          = 19.849 / 5

          = 3.9694

          = 3.97 (Approximately)

As we can see that the Option (A) 3.97 correctly matches the answer.

So the correct answer is Option (A) 3.97.

The two triangles illustrated below are similar. What are the values of x and y?

Answers

Answer: A
Explanation: using the common ratio we can solve this. 24:8 = x:4
24 divided by 8 is 3.
Therefore x divided by 4 should be 3 too.
4 multiplied by 3 is 12, so x = 12.
For y:
When triangles are similar, the angles are always the same. So y is simply 40 degrees.

1). Mean: 14.2

  Median: 13.5

Step-by-step explanation:

To calculate the mean, sum all values and divide by the number of values:

(13+16+14+17+13+12) / 6 ≈ 14.2

To calculate the median, order the values from small to large and take the middle value. If there is no middle. average the two values in the middle:

12,13,13,14,16,17

The median is (13+14)/2 = 13.5.

Using this explanation you should be able to find the rest.
