□+□+□=30 Fill in the boxes using 1,3,5,7,9,11,13,15 You can also repeat the number?

adelina 88 [10]

It is impossible to get the result of 30 using just odd numbers in the blanks.

Using factorials, we get 3! + 11 + 13 = 30 or 3! + 9 + 15 = 30

Solution:

----- + ------ + ------- = 30

We have to fill with numbers 1, 3, 5, 7, 9, 11, 13, 15 to get 30

We can also repeat the number

Given are the set odd numbers like 1, 3, 5, 7, 9, 11, 13, 15

We need three numbers to fill in the box to get 30

When three odd numbers are added, it results in odd number

But we should get 30, which is a even number

So it is impossible to get the result of 30 using just odd numbers in the blanks.

Using tricks, some of solutions are:

We can use factorial

3! + 9 + 15 = 6 + 9 + 15 = 30

3! + 11 + 13

So, 6 + 11 + 13 = 30

A company charting its profits notices that the relationship between the number of units sold, x, and the profit, P, is linear.

scoundrel [369]

Answer:

P(x) = 58x - 8,500

Step-by-step explanation:

The profit function can be modeled based on the two given points of format (P, x) that are ($1360, 170) and ($4260, 220). The slope of the function is:

$m=\frac{4,260-1,360}{220-170}\\ m=58$

Applying the general form of a linear equation, the profit function is:

$P-P_0 = m*(x-x_0)\\P - 1,360=58*(x-170)\\P(x) = 58x -8,500$

The profit as a function of units sold is P(x) = 58x - 8,500.
