Answer:

Each bag of pretzels costs $1.75

Step-by-step explanation:

Let the cost of 1 box of popcorn be $x

Let the cost of 1 bag of pretzel be $y

_______________________________________

A customer buys 2 boxes of popcorn and 1 bag of pretzels for $6.75.

cost of 2 box of popcorn =2*$x = $2x

sum of cost 2 boxes of popcorn and 1 bag of pretzels in terms of x and y

2x + y = 6.75    equation A

__________________________________

Another customer buys 1 box of popcorn and 2 bags of pretzels for $6.00

cost of 2 box of pretzel =2*$y = $2y

sum of cost of 1 box of popcorn and 2 bags of pretzels in terms of x and y

x + 2y = 6 equation B

x = 6 - 2y

substituting this value of x in equation A

2(6 - 2y) + y = 6.75  

=> 12 - 4y + y = 6.75

=> -3y = 6.75 - 12 = -5.25

=> y = -5.25/-3 = 1.75

Thus,  Each bag of pretzels costs $1.75

The Answer is g.  I may be wrong.

Answer:

Step-by-step explanation:

One

Part A

5, -3*5, (-3)^2 * 5, (-3)^3*5, (-3)^4 * 5

5, - 15, 45, -135, 405

Part B

Second term = -15

Fourth term = -135

The difference = -15 - (-135) = 120

Two

(4 + 2)*(6-2)/(-1)

(8/2) * (5 + 1) * (2 - 1)/(-1)

(16/4) * (3+3) * (2 -1) / (- 1)

Answer:

- 3, - 11, - 35, - 107

Step-by-step explanation:

Using the recursive formula with f(1) = - 3 , then

f(2) = - 2 + 3f(1) = - 2 + 3(- 3) = - 2 - 9 = - 11

f(3) = - 2 + 3f(2) = - 2 + 3(- 11) = - 2 - 33 = - 35

f(4) = - 2 + 3f(3) = - 2 + 3(- 35) = - 2 - 105 = - 107

Thus the first four terms are

- 3, - 11, - 35, - 107

We know that m<JKL = m<JKM + m<MKL

Let's substitute the values from the picture into our equation above.

10x - 11 = 43 + 8x - 20

Combine like terms.

10x - 11 = 8x + 23

Subtract 8x from both sides and add 11 to both sides.

2x = 34

Divide both sides by 2

x = 17

m<MKL = 8x - 20 = 8(17) - 20 = 136 - 20 = 116 degrees.

m<JKL = 10x - 11 = 10(17) - 11 = 170 - 11 = 159 degrees.

I even tried this and couldn't figure it out

Number of bracelets she can make from 15 1/6 = 91/6 foot of string is :

[tex]n_1=\dfrac{\dfrac{91}{6}}{\dfrac{1}{2}}\\\\n_1=30.33[/tex]

So, number of bracelets from 15 1/6 foot string are 30.

Now,

Number of bracelets she can make from 12 1/3 = 35/3 foot of string is :

[tex]n_2=\dfrac{\dfrac{35}{3}}{\dfrac{1}{2}}\\\\n_2=23.33[/tex]

Number of bracelets from 12 1/3 foot string are 23.

Therefore, total number of bracelets she can make is 23 + 30 = 53.

Hence, this is the required solution.

Answer:

The correct option is;

Mike's measurement are more precise and more accurate

Step-by-step explanation:

The given information are;

The mass of the measured bottle = 16-ounce

The record of the measurements made by Mike are;

16.4 oz

15.2 oz

15.8 oz

The record of the measurements made by Teegan are;

16.34 oz

16.59 oz

15.13 oz

From the two measurements, we have;

The precision of a measurement depends on how close the values of the measurement are to one another, therefore, we have;

For Mike, the precision is given as follows

16.4 - 15.2 = 1.2

16.4 - 15.8 = 0.6

15.8 - 15.2 = 0.6

Total difference = 1.2 + 0.6 + 0.6 = 2.4

For Teegan , the precision is given as follows

16.59 - 16.34 = 0.25

16.59 - 15.13 = 1.46

16.34 - 15.13 = 1.21

Total difference = 0.25 + 1.46 + 1.21 = 2.92

Therefore, Mike's measurements are more precise than Teegan's measurements

The accuracy of the measurement is the amount of closeness the measurements are to a given value

In the question, the given value is 16-ounces of the volume of the bottle

Therefore, by the mean absolute deviation from the 16-ounce of the bottle, we have;

For Mike;

[tex]Mean \ absolute \ deviation = \dfrac{\left | 16.4 - 16 \right | + \left | 15.2 - 16 \right | + \left | 15.8 - 16 \right | }{3} = 0.533[/tex]

For Teegan, we have;

[tex]Mean \ absolute \ deviation = \dfrac{\left | 16.34 - 16 \right | + \left | 16.59 - 16 \right | + \left | 15.13 - 16 \right | }{3} = 0.6[/tex]

Therefore, Mike's measurement is more accurate than Teegan's measurement.

Which gives;

Mike's measurement are more precise and more accurate.

Answer:

Mike’s measurements are more accurate, but Teegan’s measurements are more precise.

Step-by-step explanation:

the no of girls (320-180)=140

a) ratio of no of boys and girls=180/140=9/7=9:7

b)ratio of boys and total pupil=180/320=9/16=9:16

c) ratio of the girls and pupils=140/320=7/16=7:16

Answer:

b)9:16 (9 being boys, 16 being the total pupils)

c)7:16 (7 being girls, 16 being the total pupils)

Step-by-step explanation:

a) No. of girls= 320-180

=140

Boys: Girls

180 : 140 [ ÷ 20]

9 : 7

Answer: your answers are correct

x = 10

PT = 34

Step-by-step explanation:

PT = 4x - 6 and TQ = 3x + 4

if PT = TQ

4x - 6 = 3x + 4

4x - 3x = 4 + 6

x = 10

PT = 4x - 6

PT = 4 (10) - 6

=40 - 6

PT = 34

The value of PT = 34

Step-by-step explanation:

Hey there!!!

Here,

Firstly, Shift n to right side and -4 to the left side, because we always try to have variable as positive.

[tex] - 8+4 = + 5n-n[/tex]

Now, Simplify them.

[tex] - 8 + 4 = 5n - n[/tex]

[tex] - 4 = 4n[/tex]

You should divide now.

[tex]n = \frac{ - 4}{4} [/tex]

Therefore the value of n is -1.

{ As now you can keep it on left side. We generally find the vallue of variable by keeping it on left side. But we kept it right side in solution to avoid our confusion because if we kept it on left side and you would get harder to find the value at last as we need to transpose (-) to the right side value of n}.

Hope it helps...
