I need answer ASAP!

Mathematics
1 answer:
aalyn [17]3 years ago
7 0

Answer:

no solution

Step-by-step explanation:

when you substitute y for -2x+4 the equation is false

how I solved this:

1. substitute y for -2x+4

6x+3(-2x+4)=-12

2. distribute the 3

6x+-6x+12=-12

3. combine like terms

12=-12

this is incorrect because 12 does not equal -12, so there is no solution

14. The range of the data 6, 8, 16, 22, 8, 20, 7, 25 is __________.
maks197457 [2]

Answer:

The range of the data is 19.

Step-by-step explanation:

To solve this problem, we must remember that to calculate the range, we subtract the smallest data point in the set from the largest data point.  In this case, the largest number is 25 and the smallest number is 6.

Therefore the range is:

25 - 6

= 19

Hope this helps!

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
