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.

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?
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%

Convert the equation to Standard Form.
y=2(x+1)^(2)-4
Answer:
y = 2x^2 + 4x - 2
Step-by-step explanation:
y=2(x+1)^(2)-4 is in vertex form. We want the same equation in standard form, which looks like y = ax^2 + bx + c.
Perform the indicated multiplication (squaring of x + 1):
y = 2(x^2 + 2x + 1) - 4, or
y = 2x^2 + 4x + 2 - 4, or
y = 2x^2 + 4x - 2 This is in the standard form of a quadatic.

A plane traveled 1092 miles to Riyadh and back. The trip there was with the wind. It took 6
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.
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

Solve the system of linear equations by substitution.
[tex] \large{\red{\underline{\bf{Required \: Solution \: : }}}} [/tex]
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.

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.
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
