Given: -7(x+2)+4x=6(2x-4) prove: x=2/3

Answers

Answer 1

Answer:

2/3

Step-by-step explanation:

multipy (X+2) by 7 the you multiply (2x-4) by 6 I.e

-7×X- (-7×2)+4x=6×2x-6×4

-7x-14+4x=12x-24

collect like terms

-7x+4x-12x=-24+14

-15x=10

divide both side by -15, so that X can stand alone

-15x/-15=-10/-15

-15 cancels -15, minus cancels minus

X=10/15

X=2/3

The train journey from Euston
to Bimingham is an hour and 10 minutes.

Trains to Birmingham run at the following times: 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.

The meeting venue in Birmingham is a 5-minute walk from the station.

What is the latest time that Annabelle can leave home, if she is to make it on time for
the meeting in Birmingham

Show your work.

Please HELP!!! DUE TODAY!!
Thank you so much.

Answers

Answer:

7:45

Step-by-step explanation:

work backwards from 10:30!

u need 5 min to walk from meeting place to station, therefore u need to done riding the train by 10:25.

then u know that the train is an hour and 30 min, therefore u have to ride the train before or at 8:55 (10:25 minus an hour and a half)

the latest time for the train to leave is 45 min past the hour. therefore you will ride the 8:45 train.

since we already know that we are riding the 8:45 train by latest, you have to leave an hour early to get to the station. so you need to leave home by 7:45.

hope i was helpful !

The latest time that Annabelle can leave home is the she leaves home and she won't be late for her meeting

Time of meeting = 10.30am

Time she will spend before getting to meeting:

home to get to Euston Rail Station = 1 hour

train journey from Euston to Bimingham = 1 hour 10 minutes

Trains to Birmingham = 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.

The latest time is 45 minutes

Walk from the meeting venue in Birmingham from the station = 5 minute walk

Total time = 1 hour + 1 hour 10 minutes + 45 minutes + 5 minutes

= 3 hours

Counting 3 hours backward from 10:30 am = 7:30 am

Therefore, the latest time Annabelle can leave home is 7:30 am

6. You earn 8% commission on sales. What is the commission if the sales
were as follows. 4 items at $1200,7 items at $650; 7 items at $600, and 6
items at $450? (no commas)*

Answers

Answer:

The total commission is=$1300

Step-by-step explanation:

The commission rate is a fixed number that applies to all the sales made by a salesperson. In our problem, the fixed commission rate is 8%, and the sales were as follows:

4 items at $1200 for a total of $4800. The commission is:

8% of 4800 = 0.08*4800 = $384

7 items at $650 for a total of $4550. The commission is:

8% of 4550 = 0.08*4550 = $364

7 items at $600 for a total of $4200. The commission is:

8% of 4200 = 0.08*4200 = $336

6  items at $450 for a total of $2700. The commission is:

8% of 2700 = 0.08*2700 = $216

The total commission is: $384+$364+$336+$216=$1300

The total commission is=$1300

Judy’s Cake Shop makes fresh cakes to customer orders. After receiving the order by Judy’s assistant, which takes 2 minutes, Judy then takes 8 minutes to mix the ingredients for the cake and loads a cake pan for baking. Then the cake is put into the oven for 30 minutes. The oven can hold three cakes at one time. When the cake is taken out of the oven, it is cooled for 1 hour. The assistant then takes 2 minutes to pack the cake for pickup and bills the customer, which takes 3 minutes. a. What is the capacity of the process, and what is the bottleneck? b. What is the throughput time for a typical cake? c. If on average five orders are taken per hour, how many cakes are there in the process (on average)?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Time taken to receive order = 2 minutes

Ingredient mixing and cake loading = 8 minutes

Baking time = 30 minutes

Number of cakes oven can hold at a time = 3

Cooling time = 1 hour = 60 minutes

Cake packing = 2 minutes

Billing customer = 3 minutes

a. What is the capacity of the process, and what is the bottleneck?

The capacity of the process:

Within an hour : two bakings can be done =(30 minutes * 2) = 60 minutes

Also oven can hold 3 cakes, so, 3 cakes can be baked at a time.

Hence, 3 cakes in 30 minutes ;

6 cakes in an hour;

Hence, capacity of the process is 6cakes per hour.

The bottleneck is the oven, because if the number of ovens were to be increased, the process capacity will increase, similarly, if one of the oven gets faulty, then the process capacity reduces further.

b. What is the throughput time for a typical cake?

The throughput time, is the summation of all the time taken to fully complete an order :

Receipt of order + mixing + baking + cooling + packing + billing

2 + 8 + 30 + 60 + 2 + 3 = 105 minutes

c. If on average five orders are taken per hour, how many cakes are there in the process (on average)?

(Throughput time / 60) * average number of order

(105/60) * 5

= 1.75 * 5

= 8.75
