I took the quiz and got it correct

The average of your 3 quiz grades is 17 points. Two of your quiz grades are 14 points and 19 points. Write and solve an equation to find the score of your third quiz.

Answers

Answer:

The equation would be 14+19+x=51, and the 3rd quiz score would be 18.

Step-by-step explanation:

To get to the average, you have to add all the quiz scores and divide by the number of quizzes. If you work backwards, you can multiply the average by the number of quiz scores, which is 51. Then you subtract the known test scores, and you get your answer.

OK SO I SOLVED ALL OF THIS: It costs a company $20 per box to make pocket-sized stuffed animals. The company also has a fixed manufacturing cost of $2300. The owners are trying to calculate their cost for making boxes of animals. --Function Rule: c(x) = 20b + 2300.

BUT I NEED HELP WITH THIS!!! Use your function rule to find out how many boxes of stuffed animals can the company manufacture for $5000? SHOW WORK.

basically just show the work to find out what "b" would have to be in order for the
answer to be $5,000 i would appreciate it so much :) please help this is due today :(

Answers

Answer:

The company can manufacture 135 boxes of stuffed animals for $5000

Step-by-step explanation:

To find b, substitute $5000 for c(x), so

5000 = 20b + 2300

Then subtract 2300 from both sides of the equation, so

5000 (-2300) = 20b + 2300 (-2300)2700 = 20b

Finally divide both sides of the equation by 20, so

2700/20 = 20b/20135 = b

To check your answer substitute 135 in as b...

c(x) = 20(135) + 2300c(x) = 5000

Show the work

Answers

Answer:

Step-by-step explanation:

Move -7 to the left, so make 7 positive and & move it next to 25

1. 3x = -10x +25+7

combine 25 & 7

2. 3x=-10x+32

move 10 to the side & combine with 3x

3. 3x+10x=+32

4. 13x = 32

lastly divide 32 from 13

x= 32/13 OR x= 2 6/13

Answer:x=32/13

Step-by-step explanation:

Rearrange terms−7+3=−10+25−7+3x=−10x+25

3−7=−10+25

add 7 to both sides of the equation

then Simplify

add 10 to both sides of the equation the

x=32/13

Judy has 2 3/4 bags of rock that she wants to use in her yard. Each bad will cover 310.2 sq ft. How many square feet will Judy be able to cover if she used all the bags of rocks? Round up your answer to the neatest tenth place.

Answers

Answer:

853.1 sq ft

Step-by-step explanation:

Total bags of rock = 2 3/4

Each bag will cover 310.2 sq ft

How many square feet will Judy be able to cover if she used all the bags of rocks?

Total Square feet covered = number of bags of rock × area covered by each bag

= 2 3/4 × 310.2 sq ft

= 11/4 × 310.2 sq ft

= 853.05 sq ft

To the nearest tenth

subtract 103 degrees from 180 to get 77, then add 77 and 37 together and subtract by 180

First you have to subtract 180 to 103 and you get 77 because a straight line always add up to 180, then you have to add that 77 to the 37 that is inside of the triangle and you get 114 and then you subtract 180 to 114 and you get 66 because the sum of the angles inside of the triangle is 180 degrees
The final answer is x= 66

A kitchen sink faucet streams 0.5 gallon of water in 10 seconds. A bathroom sink faucet streams 0.75 gallon of water in 18 seconds. Which faucet will fill a

3-gallon container faster?

Answers

Answer:

the kitchen sink faucet will fill the container faster than the bathroom faucet.

Step-by-step explanation:

I found the unit rate for both faucets in order to be able to compare them.

Kitchen faucet:

.5 gallons in 10 seconds = 1 gallon in 20 seconds (0.5 x 2= 1 gal, 10 sec x 2=20 seconds)

.75 gallons in 18 seconds = 1 gallon in 24 seconds (0.75 = 3/4 3/4 x 4/3=1 gallon, 18 x 4/3 = 24 seconds)

Step-by-step explanation:

Michael got a $50 gift card to an online music store. She uses the gift card to buy an album for $9.99. She also wants to use the gift card to buy some songs. Each song costs $1.29. Which of these inequalities describes this situation, where n is the number of songs Michael wants to buy?

Answers

Answer:

$9.99 + $1.29n ≤ $50

Step-by-step explanation:

Given that:

Worth of gift card = $50

Cost of album purchased = $9.99

Cost per song to purchase = $1.29

Number of songs to purchase = n

Inequality to model the situation :

Cost of album + cost per song * (Number of songs) ≤ worth of gift card

$9.99 + ($1.29 * n) ≤ $50

$9.99 + $1.29n ≤ $50

Write the equation of the line passing through (2,3) and perpendicular to y = 2/3 x + 7.

Answers

Answer:

y = 2/3x

Step-by-step explanation:

So we know, when lines are perpendicular that they share the same slope. The slope in the equation of y = 2/3x + 7 is 2/3x. So, we have our slope. Now, we just need to find our b. We plug in the point that you gave us into the equation y = mx + b.

3 = 2/3(2) + b

we multiply the denominator 3 by 2, then divide that by the numerator 2.

3 = 3 + b

subtract 3 from itself and from the opposite side of the equal side 3.

0 = b

in the end, there is no b for this equation. Our answer is

y = 2/3x
