Answer: 1.Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2.Use the exponent rule to remove grouping if the terms are containing exponents.
3.Combine the like terms by addition or subtraction.
4. Combine the constants
Step-by-step explanation:
[tex]8(5w+7) + 9 ( 4w- 7)[/tex]
The first thing we do is distribute
[tex]8(5w+7)& 9(4w-7)[/tex]
We distribute what is outside the parenthesis to everything that is inside the parenthesis
so for 8(5w+7) we do [tex]8x5w = 40w[/tex] and [tex]8x7 = 56[/tex]
so for 9 So 9(4w−7) turns into 36w+63
so now we have 40w+56+36w+−63
now combine like terms
(40w+36w)+(56+−63)=?

Consider the baggage check-in process of a small airline. Check-in data indicate that from 8 a.m. to 9:30 a.m., 360 passengers checked in. Moreover, based on counting the number of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 30.
Required:
How long did the average passenger have to wait in line?
Answer:
[tex]Average = 7.5\ mins[/tex]
Step-by-step explanation:
Given
[tex]Time = 90\ mins[/tex] i.e. 8am to 9:30am
[tex]Total\ Passengers = 360[/tex]
[tex]Average\ Passengers= 30[/tex]
Required
Determine the average waiting time
The average waiting time is calculated as:
[tex]Average = \frac{Average \ Passengers}{Total\ Passengers} * Time[/tex]
[tex]Average = \frac{30}{360} * 90\ mins[/tex]
[tex]Average = \frac{30* 90\ mins}{360}[/tex]
[tex]Average = \frac{2700\ mins}{360}[/tex]
[tex]Average = 7.5\ mins[/tex]
Hence, the average waiting time is 7.5 minutes
calculate the total distance Mary runs in one week if she runs 7/8 mile a day
Answer:
1 3/4
Step-by-step explanation:
I did 7/8 times 7/1 (7 days as a fraction) = 1 6/8 then i simplified that to 1 3/4
Total distance Mary runs in one week if she runs 7/8 mile a day is,
⇒ 49 / 8 miles
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Mary runs 7/8 mile a day.
Since, We know that;
1 week = 7 days
Now, Total distance Mary runs in one week if she runs 7/8 mile a day is,
⇒ 7 x 7/8
⇒ 49 / 8 miles
Thus, Total distance Mary runs in one week if she runs 7/8 mile a day is,
⇒ 49 / 8 miles

Mr. Kershner is a school nurse. He uses, on average, 24 self-adhesive bandages during each spring month: March, April, and May. He also knows that in June there are several field days and he will need 4 times the number of bandages for that month.
If the bandages cost 3 cents each, what is his total cost for March through June?
If the bandages cost 3 cents each, Mr. Kershner's total cost for bandages from March through June is $5.04.
What is an arithmetic operation?
Arithmetic operations is a branch of mathematics, that involves the study of numbers, the operation of numbers that are useful in all the other branches of mathematics. It basically comprises operations such as Addition, Subtraction, Multiplication, and Division.
The number of bandages used by Mr. Kershner in March, April, and May is 24 bandages each month, for a total of 24 x 3 = 72 bandages for those three months.
In June, he will need four times as many bandages as in the other months, for a total of 4 x 24 = 96 bandages.
The total number of bandages used from March through June is 72 + 96 = 168 bandages.
The cost of each bandage is 3 cents, so the total cost for 168 bandages is 168 x 3 = 504 cents, or $5.04.
Therefore, Mr. Kershner's total cost for bandages from March through June is $5.04.
