Answer:

Step-by-step explanation:

Let first group of people take x candies each

and second group of people take y candies each

5x + 7y will be total candies

5x +7y = 239 (needed to find positive solution of x,y)

now take x=38,  y =7

or x=31,   y= 12

hence lots of possibilities ,so we can not say exactly

Answer:

No! we can't, because there is no enough information (equation) to derive an exact value.

Step-by-step explanation:

From the question let x represent the number of candies each of the first five people took and y represent the number of candies each of the second seven people took.

Therefore, Given the total number of candies in the jar to be 239, we can express it mathematically as;

5x + 7y = 239 .....1

Since, there is no other information given and no other equation, then it is not possible to derive an exact value of the number of candies each of them picked.

Because, we have two variables(x and y) and one equation. To get an exact value for a simultaneous equation the number of variables must be equal to the number of equations given (e.g 2 variables and 2 equations....)

The possible values of the equation above are.

x = 38, y= 7

x = 45, y= 2

Etc.....

What is the average price of an item sold considering quantity? 12 notepads at $4.20 25 folders at $0.80 3 calculators at $19.00
Savatey [412]

Answer:

Average price = $3.185

Step-by-step explanation:

Given:

12 notepads = $4.20 each

25 folders = $0.80 each

3 calculators =  $19.00 each

Find:

Average price

Computation:

Average price = Total cost / Total number of item

Average price = [(12)(4.20) + (25)(0.80) + (3)(19)] / [12 + 25 + 3]

Average price = [(50.4) + (20) + (57)] / [40]

Average price = [127.4] / [40]

Average price = $3.185

The rate to rent a small moving van is $30 per day, plus $0.25 per mile. The Sparkling Appliance Company rented a van because it
Zigmanuir [339]
Total rental cost = $390 = 2($30/day) + ($0.25/mile)x     (x=number of miles)
                                                                                          330
Then 390 = 60 + 0.25x     =>    330 = 0.25 x    =>   x = ------------
                                                                                           0.25

x comes out to 1320 miles.

Ierofanga [76]

Answer:

19.2x+96 units

Step-by-step explanation:

The perimeter of a square is 4 times the length of one side.

The length of the sides of a square is given by the expression 4.8x+24

To find the perimeter, we multiply this expression by 4.

Perimeter=4(4.8x+24)

We expand to obtain:

Perimeter=4*4.8x+4*24

This simplifies to:

Perimeter=19.2x+96

Brian rolls 2 fair dice and adds the results from each. Work out the probability of getting a total that is prime. Answer THIS P
Vladimir [108]

Answer:

5/12 or 15/36

Step-by-step explanation:

Since he rolls two dice, he has a total probability of 6 times 6 = 36. The pairs, that he could add up to primes are (1,1), (2,1) * 2 (since he can get 1,2 as well), (1,4) * 2, (2,3) * 2, (3,4) * 2, (5, 2) * 2, (6,1) * 2, (5, 6) * 2. This is 1 + 2 + 2 + 2 + 2 + 2 + 2 + 2, which is equal to 15. This is a total of 15/36 possible ways, which is also equal to 5/12.
