You recently spent $22 to purchase a notebook, a box of pencils, and a package of pens. The box of pencils costs $2 less than the notebook. The package of pens costs 3 times as much as the box of pencils. Write and solve an algebraic equation to find the cost of each item you purchased.
Answers
Answer:
The answer is down below:
Step-by-step explanation:
Notebook: 22-x
Pens: (22 - x - 2) x 3.
Pencils: 22 - x - 2.
We use x for notebooks because it is the only item that doesn't have an "equation" for us to solve so we use "x" instead. hope this helped you out.

What is the value of the expression 10-(1/2)^4•48
Answers
Answer:
If so, order of operation is coming into play
PEMDAS
P is the parenthesis and E is the exponent..... looks we got a 2 for 1 special solve.
(1/2)4
First
The exponent is 4 which means write
1/2
4 times
1 × 1 × 1 × 1 = 1
2 × 2 × 2 × 2 = 16
So our fraction is 1/16
10 - 1/16 - 48
now we have M D which is multiplication and division what is
1/16 - 48
now we just have 10 - 3
We don't have A ( addition ) so skip it
We do have S ( subtraction )
10 - 3 = 7.

The seniors and juniors at Sweet Valley High School are going on a trip to Busch
Gardens. The seniors filled 12 vans and 12 buses with 564 total students. The juniors
filled 6 vans and 13 buses with 492 students. How many students were in each van? In
each bus?
Solve the system of equations
Answers
Answer:
buses can hold 30 and vans can hold 17.
Step-by-step explanation:
Let the amount a van can hold be v and the amount a bus can hold be b.
12 vans and 12 buses totals 564: 12v + 12b = 564 (equation 1)
6 vans and 13 buses totals 492: 6v + 13b = 492 (equation 2)
Subtract 2 times equation 2 from equation1, we get 14b = 420.
Thus, b = 30.
Since 12v + 12b = 564, plugging in b=30, 12v + (12)(30) = 564, so v = 17.
The number of students filled in the van is 17, and number of students filled in the bus is 30.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as linear equation in one variable.
Let's suppose the total number of students in van is x, and the number of students in the bus is y
Now for the first scenario we can frame a linear equation in two variables such as:
12x + 12y = 564 or
x + y = 47 ....(1) (divide by 12 on both sides)
For the second scenario the linear equation in two variables becomes:
6x + 13y = 492 ....(2)
From the equation (1) take the value of x and plug in the equation (2), we get:
6(47-y) + 13y = 492
282 - 6y +13y = 492
7y = 492-282 (subtract 282 from both sides)
7y = 210
y = 30
Put this value in the equation (1), we get:
x + 30 = 47
x = 17 (subtract by 30 from both sides)
Thus, the number of students filled in the van is 17, and number of students filled in the bus is 30.

find the median and mean 42,15,14,48,39
Answers
Answer:
Hello! the answer is 39 and 32
Step-by-step explanation:
To find the median we need to reorder the numbers from lowest to highest:
14,15,39,42,48
The one in the middle is the median! If there happens to be an even number, take the two middle numbers add them, together and divide them by 2.
To find the mean (also know as the avergae) we need to add all the numbers together and divide by the number of values that are present:
42+15+14+48+39 = 158
158/ 5 = 31.6 or 32

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah, a total of 17 people took the trip. She was able to purchase coach tickets for $350 and first-class tickets for $.1100 She used her total budget for airfare for the trip, which was $ 12,030. How many first-class tickets did she buy? How many coach tickets did she buy?
Answers
Answer:
Sarah bought 9 coach tickets and 8 first class tickets.
Step-by-step explanation:
Since Sarah took the advertising department from her company on a round trip to meet with a potential client and, including Sarah, a total of 17 people took the trip, if she was able to purchase coach tickets for $ 350 and first-class tickets for $ 1100, and she used her total budget for airfare for the trip, which was $ 12,030, to determine how many first-class and coach tickets did she buy, the following calculation must be performed:
10 x 350 + 7 x 1100 = 3500 + 7700 = 11200
9 x 350 + 8 x 1100 = 3150 + 8800 = 11950
So Sarah bought 9 coach tickets and 8 first class tickets.

Answers
Answer:
m∠1 = 37°
Step-by-step explanation:
if m∠5 = 137 then m∠2 = 43 (supplementary angles)
if m∠7 = 100 then m∠3 = 100 (vertical angles)
m∠1 + m∠2 + m∠3 = 180°
m∠1 + 43 + 100 = 180°
