3x+15x = 180
18x = 180
    x = 10

10(x+y) + 3x = 180
10x + 10y + 3x = 180
13x + 10y = 180
13(10) + 10y = 180
130 + 10y = 180
10y = 50
    y = 5

Luke's Bakery recently spent a total of $69 on new equipment, and their average hourly operating costs are $15. Their average ho
WINSTONCH [101]

Answer:

It will take the bakery 2.875 hours to make back the amount invested.

The total expenses and receipts, both will = $112.125

Step-by-step explanation:

Given:

Cost of equipment = $69

Operation cost per hour = $15

Average hourly receipts = $39

To find how many hours will it take for the Bakery to make back the amount invested and what would the total expenses and receipts both equal

Solution:

Let the bakery take t hours to make back the amount invested.

Operation cost for t hours in dollars will be = 15t

Equipment cost = $69

Total expenses in dollars can be given as = 15t+69

Receipts for t hours in dollars will be = 39t

<em>Since the bakery makes up the amount invested in </em>t<em> hours, so the amount in expenses must be equal to the total receipts for </em>t<em> hours.</em>

Thus, we have:

39t=15t+69

Subtracting both sides by 15t

39t-15t=15t-15t+69

24t=69

Dividing both sides by 24.

\frac{24t}{24}=\frac{69}{24}

∴ t=2.875

So, in 2.875 hours the bakery will be able to make back all the investment.

Total expenses in 2.875 hours will be = 15(2.875)+69=43.125+69=\$112.125

Total receipts will be the same and can be given as = 39\times 2.875 = \$112.125

Which shows one way to determine the factors of x^3-12x^2-2x+24 by grouping
dezoksy [38]

Answer:

(x - 12)(x² - 2)

Step-by-step explanation:

Given

x³ - 12x² - 2x + 24 ( factor the first/second and third/fourth terms )

= x²(x - 12) - 2(x - 12) ← factor out (x - 12) from each term

= (x - 12)(x² - 2)
