Solve for the value of n.​

Answer:

pen = $1.20,  pencil = $0.50

Step-by-step explanation:

let x = pen

let y = pencil

create system of equations:

3x + 6y = 6.60        [can be simplified to be x + 2y = 2.20]

5x + 8y = 10.00

substitution method:

x = 2.2 - 2y

5(2.2 - 2y) + 8y = 10

11 - 10y + 8y = 10

-2y = -1

y = 1/2

solve for 'x':

3x + 6(1/2) = 6.6

3x + 3 = 6.6

3x = 3.6

x = 1.2

Step-by-step explanation:

Cost - 500

Marked Up - 250

Margin - 71.4286

MxCxMA= $1,750

This may seem confusing, but its $1,750 for the new price, and the equation is:

M= Marked

C= Cost

MA= Margin

The new price of the television is $1750.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A television that costs $500 is marked up 250%.

So, the new price is

= 500 + 250% of 500

= 500 + 250/100 x 500

= 500 + 1250

= $1750

Hence, the new price of the television is $1750.

Answer:

C. 19a + 11b

Step-by-step explanation:

Distribute into the parentheses.

3(5a + b) + 4(a + 2b)

= 15a + 3b + 4a + 8b

Add like terms.

15a + 3b + 4a + 8b

19a + 3b + 8b

= 19a + 11b

Hope that helps.

Hey there!

“Simplify 3(5a + b) + 4(a + 2b)”

FIRST you have to DISTRIBUTE

3(5a + b) + 4(a + 2b)

3(5a) + 3(b) + 4(a) + 4(2b)

3(5a) = 15a

3(b) = 3b

4(a) = 4a

4(2b) = 8b

“15a + 3b + 4a + 8b”

SECOND: COMBINE your LIKE TERMS

(3b + 8b) + (15a + 4a)

(3b + 8b) = 11b ⬅️ BACK number

(15a + 4a) = 19a ⬅️ FRONT number

ALL OF YOUR TERMS/NUMBERS ARE POSITIVE SO WE DON’T HAVE TO FIX ANYTHING

Answer: C. 19a + 11b ☑️

Good luck on your assignment and enjoy your day!

Answer:

A=81

Step-by-step explanation:

Answer:

81

Step-by-step explanation:

36/4=9

9*9=81

Answer:

Step-by-step explanation:

From the question given in the picture,

a). Since, NR bisects a straight angle ∠MNP,

  ∠MNR ≅ ∠PNR

  m∠MNR + m∠PNR = 180°

  2(m∠MNR) = 180°

  m∠MNR = 90°

  Therefore, ∠MNR and ∠PNR are the right angles.

  Since, QN divides ∠MNR in two parts,

  Therefore, ∠QNR will be an acute angle (less than 90°).

  ∠MNR + ∠SNR = ∠MNS

  90° + ∠SNR = ∠MNS

  Therefore, m∠MNS will be more than 90°.

    ∠MNS will be an obtuse angle (greater than 90°).

(b). Since, NR divides ∠MNP and ∠QNS,

    ∠MNR ≅ ∠PNR

     ∠QNR ≅ ∠SNR

     ∠MNQ ≅ ∠PNS

(c). m∠MNR = 90°

     Since, NR bisects ∠QNS,

     ∠QNR ≅ ∠RNS

     m∠QNR = m∠RNS = 30°

     m∠QNR + m∠RNS = 30° + 30°

     m∠QNR + m∠RNS = 60°

     m∠QNS = 60° [Since, m∠QNS = m∠QNR + m∠RNS]

     m∠QNP = m∠QNS + m∠SNP

     m∠QNP = m∠QNS + (m∠PNR - m∠SNR)

     m∠QNP = 60° + (90° - 30°) = 120°

Answer:

[tex]\dfrac{48}{4}=12[/tex]

Step-by-step explanation:

Given that:

Dylan plays basketball.

In the season, he scored 48 points in total in the first four games of the season.

To find:

The equation to represent the average number of points scored per game.

Solution:

Average is the term used to find one number which can be used to represent a list.

It is usually the mid value.

Average can be found by using the following formula:

[tex]\text{Average =} \dfrac{\text{Sum of all the observations}}{\text{Number of observations}}[/tex]

Here, Sum of all the observations is the total score which is given as 48.

Number of observation is nothing but the number of games which is given as 4.

Therefore, the equation to find the average can be written as:

[tex]Average = \dfrac{48}{4}\\ \Rightarrow \bold{Average = 12}[/tex]

Answer:

Step-by-step explanation:

in a right triangle a^2+b^2=c^2,

where a and b are the legs

where c is the hypothenuse

9^2= b^2+3^2

81-9=b^2

b^2=72

b=8.48

Answer:

Step-by-step explanation:

Givens

a = ?

b = 3

c = 9

Formula

a^2 + b^2 = c^2

Solution

a^2 + 3^2 = 9^2

a^2 + 9 = 81

a^2 = 81 - 9

a^2 = 72

Now the tricky part. Are you required to give the exact answer which is

a = √72 = 6√2

Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.

So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 98 dollars.

The solution would still clear your concept though.

Answer:

Please check the explanation.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the function

c(x) = 18x -10

comparing with the slope-intercept form of the line equation

According to the function equation,

Assuming the total cost i.e. c(x) = $98

In order to determine the value of x, set c(x) = 98

i.e.

98 = 18x -10

switch sides

18x - 10 = 98

add 10 to both sides

18x - 10 + 10 = 98 + 10

18x = 108

Divide 18 to both sides

18x/18 = 108/18

x = 6

Therefore, if you can buy x = 6 if you pay 98 dollars.

1) The quotient is 6.

2) The quotient is 9/10.

Answer:

5.5 min

Step-by-step explanation:

At time t=0 you have 72 grams

at time t = 22 min you have 4.5 grams.

Now

4.5/72 = (1/2)^(t/half-life)

and t=22, so

4.5/72 = (1/2)^(22/half-life)

taking log of both sides:

log(4.5/72)=(22/half-life)log(1/2)

solving for half-life gives half-life = 11/2 = 5.5min
