A model with 3 rows of 5 squares and 3 rows of 3 squares. Use the model to find the missing number in the pair of equivalent expressions. 15 + 9 = ?(5 + 3) what number is missing from the expression?.

Answers

Answer 1

The missing number in the pair of equivalent expressions is 9.

To solve this problem, you can use the model provided to represent the expressions 15 + 9 and 5 + 3.

For the expression 15 + 9, you can place 15 in the first row of five squares and 9 in the second row of five squares, like this:

[15] [9]

For the expression 5 + 3, you can place 5 in the first row of three squares and 3 in the second row of three squares, like this:

[5] [3]

Then, you can use the model to find the missing number in the pair of equivalent expressions. Since the two expressions are equivalent, the missing number should be in the same position as the number 3 in the second row of the model.

If you look at the first expression, you can see that the missing number is in the same position as the number 9. Therefore, the missing number in the pair of equivalent expressions is 9.

Valentina's family is planning to have a party for her quinceanera. They are considering two different locations to rent for her party. Casa Lucia charges a $200 one-time rental fee plus $500 per hour. The Silver Fox charges $200 per hour plus a $1,100 one-time rental fee. Explain what the solution to the system of equations represents in this real-world context.

Answers

Answer:

number of hours = 3 hours

Step-by-step explanation:

Let

x = number of hours

Casa Lucia = 200 + 500x

Silver Fox = 1,100 + 200x

To solve the equation, equate both cost of rent

Casa Lucia = Silver Fox

200 + 500x = 1,100 + 200x

200 - 1,100 = 200x - 500x

-900 = - 300x

x = -900 / -300

x = 3 hours

number of hours = 3 hours

The solution to the system of equations in this real-world context represents the number of hours both locations can be rented with the same cost.

It means both locations cost the same if rented for 3 hours each

Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft2 and she painted 288 ft2 yellow, what percent of the room did she paint green?

Answers

Answer:

Total percent of the room did she paint green = 60%

Step-by-step explanation:

Given - Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft² and she painted 288 ft² yellow.

To find - What percent of the room did she paint green ?

Proof -

Given that,

The surface area of the walls in her room = 720 ft²

Total area painted in yellow color = 288 ft²

So,

Total area painted in green color would be = 720 - 288 = 432 ft²

Now,

Let the total percent green color painted = x

So,

720 × x% = 432

⇒[tex]720*\frac{x}{100} = 432[/tex]

⇒ x = [tex]\frac{432*100}{720}[/tex] = 60

∴ we get

Total percent of the room did she paint green = 60%

Solve the system of linear equations by substitution.

Here we have been provided with two equations and we have to solve them by substitution method and get the value of x and y.

y = x - 4 (Equation No 1)y = 4x - 10 (Equation No 2)

Here we have been already provided a temporary value of y in first equation so let us substitute in the second equation.

[tex]: \implies \: \sf{y \: = \: 4x \: - \: 10}[/tex]

[tex]: \implies \: \sf{x \: - \: 4 \: = \: 4x \: - \: 10}[/tex]

[tex]: \implies \: \sf{x \: = \: 4x \: - \: 10 \: + \: 4}[/tex]

[tex]: \implies \: \sf{x \: = \: 4x \: - 6}[/tex]

[tex]: \implies \: \sf{x \: - 4x \: = \: - 6}[/tex]

[tex]: \implies \: \sf{ - 3x \: = \: - 6}[/tex]

[tex]: \implies \: \sf{ \cancel - \: 3x \: = \: \cancel- \: 6}[/tex]

[tex]: \implies \: \sf{ 3x \: = \: 6}[/tex]

[tex]: \implies \: \sf{ x \: = \: \dfrac{6}{3} }[/tex]

[tex]: \implies \: \sf{ x \: = \: \cancel\dfrac{6}{3} }[/tex]

[tex]: \implies \: \boxed{\bf{ x \: = \:2 }} \pink\bigstar[/tex]

Therefore, value of x is 2..!!

Finding out value of y :

Here we would substitute the value of x which we got as 2 in the first equation inorder to get the value of y.

[tex]: \implies \: \sf{ y \: = \: x \: - \: 4 }[/tex]

[tex]: \implies \: \sf{ y \: = \: 2 \: - \: 4 }[/tex]

[tex]: \implies \: \boxed{\bf{ y \: = \:-2 }} \pink\bigstar[/tex]

Therefore, value of y is -2.

hours. The trip back was into the wind. The trip back took 7 hours. Find the speed of the plane
in still air and the speed of the wind.

Answers

Answer:

Step-by-step explanation:

p and s was are the speeds of the plane and wind, respectively.

Traveling with the wind, the plane moves p+w miles per hour.

p+w = (1092 miles)/(6 hours) = (182 miles)/hour

Traveling against the wind, the plane moves p-w miles per hour.

p-w = (1092 miles)/(7 hours) = (156 miles)/hour

Add the equations together

p+w = 182

p-w = 156

—————-

2p = 338

p = 169 miles per hour

w = p-156 = 13 miles per hour

Perform the indicated multiplication (squaring of x + 1):

y = 2(x^2 + 2x + 1) - 4, or

A line passes through the point (1,-6) and (-5, -3) In Farmland, only Carlos and Madeline can raise free-range chickens on their farms. Assume that Carlos and Madeline can collect and sell a large quantity of eggs at no cost and that free-range eggs produced outside Farmland cannot be transported into the town for sale. The following questions will walk you through the process of computing the equilibrium result using the Stackelberg model. Suppose that, in this market, Carlos decides how many eggs per day he is going to produce, and then Madeline makes her decision after observing Carlos's quantity choice. The market demand for eggs is given by Q = 16 - P. Use the purple line (diamond symbol) on the following graph to illustrate Madeline's best-response function as determined by the quantity of eggs Carlos decides to produce. Since Carlos knows how Madeline will react depending on the quantity of eggs he sells, he can internalize this effect by deriving the net demand for his eggs. In the first blank column of the following table, enter the quantity of eggs Madeline will sell, given each of the quantities listed for Carlos's production. Then add these quantities to solve for the total production of eggs and enter the sum in the Total Production column. Finally, determine the market price that will emerge, given the total production, and enter that price in the final column.The following graph shows Carlos's marginal cost (MC) for producing eggs. Use the green point (triangle symbol) to plot the net demand (ND) for Carlos's eggs based on the prices listed in the preceding table. Then, use the grey line (star symbol) to graph Carlos's marginal revenue (MR) curve. Finally, use the black point (plus symbol) to indicate Carlos's profit-maximizing level of output and the resulting market price for a gross of eggs. Note: Dashed drop lines will automatically extend to both axes. True or False: If Carlos cannot commit to the output level you determined, then Carlos and Madeline will both end up producing around 5 gross of eggs.
