Answer:

(22, 5)

Step-by-step explanation:

Given the 2 equations

x = y + 17 → (1)

x = 4y + 2 → (2)

Substitute x = 4y + 2 into (1)

4y + 2 = y + 17 ( subtract y from both sides )

3y + 2 = 17 ( subtract 2 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

Substitute y = 5 into either (1) or (2) and solve for x

(1) : x = 5 + 17 = 22

Solution is (22, 5)

Four different sets of objects contain 2,5,6, and 7 objects, respectively. How many unique combinations can be formed by picking

Ilia_Sergeevich [38]

There are 2 choices for the first set, and 5 choices for the second set. Each of the 2 choices from the first set can be combined with each of the 5 choices from the second set. Therefore there are 2 times 5 combinations from the first and second sets. Continuing this reasoning, the total number of unique combinations of one object from each set is:
$2\times5\times\times6\times7=420\ combinations$

luda_lava [24]

Answer:

$\frac{g}{8}-17$ games

Step-by-step explanation:

Employees: 8

Sales last month: g

Average: $\frac{totalGames}{Employees}$

To find out how many games Chris sold, we have to take the average and subtract 17.

$\frac{g}{8}-17$

Since there are no more values we can use, this is as simple as we can get it. If we knew how many games they sold last month, we could get an exact answer for Chris using this expression.
