I need help with this problem
Answer:
(A)
Step-by-step explanation:
I good way to solve this is to test out each answer. We can do this by setting it equal to the expression given in the question.
Let start with (A). If [tex]x + 2y + x + 2[/tex] is equivalent to (A) then we can say
[tex]x + 2y + x + 2 = 2(x+y+1)[/tex]
And we can combine the two [tex]x[/tex]'s on the left side to make.
[tex]2x + 2y + 2 = 2(x+y +1)[/tex]
Now by expanding the right side we get
[tex]2x + 2y + 2 = 2x + 2y + 2[/tex]
which is the same thing so there are both equal!
Now lets test (B). We start off by doing the same thing as (A) except with the equation for (B)
[tex]2x + 2y + 2 = 2x + 4y + 4[/tex]
Now this doesn't look quite right, on the left side we have two [tex]y[/tex]'s but on the right we have four. This means our equation is unbalanced which means they are unequal! So it can't be (B)
So the only correct answer is (A)!

Answer:
39
Step-by-step explanation:
This weird notation just means we are going to put one equation inside the other, and then solve.
Makes more sense when you write it like this:
g ( f ( x ) )
To solve, we are going to take the 3, plug it into the f ( x )
g ( f ( 3 ) )
^ This makes it a lot easier to understand what we have to do.
----------------------------------------------------------------------------------------------------------
Ok, so now we evaluate f ( x ) at 3.
4 ( 3 ) - 2
f( x ) = 10
Then we plug it into g ( x )

Answer:
See explanation
Step-by-step explanation:
Enzo’s profit over the last few months:
In December, he made profit $900;In January, his his profit was $500; In February - unknown;In March, his loss was $300.Find the difference between given data
Dec - Jan [tex]\$900-\$500=\$400[/tex]
Jan - Feb [tex]\$500-\$x[/tex]
Feb - Mar [tex]\$x-(-\$300)=\$x+\$300[/tex]
If this sequence is arithmetic, then
[tex]\$500-\$x=\$x+\$300=\$400\\ \\\$x=\$100[/tex]
So, if the profit in February was $100, then this sequence is arithmetic sequence. In this case,
[tex]a_1=900\\ \\a_2=500\\ \\a_3=100\\ \\a_4=-300\\ \\...\\ \\d=-400[/tex]

a teacher is buying supplies for an upcoming art project. She buys x bottles of paint for $1.29 each. She buys 8 more canvases than bottles of
paint for $1.89 each. Her total pretax cost is $37.38. How many of each item is she buying?
If a teacher is buying supplies for an upcoming art project. She buys x bottles of paint for $1.29 each. She is buying 7 bottles of paint and 15 canvases.
What is number of items?Let's represent the number of bottles of paint she buys as x and the number of canvases she buys as x + 8.
The cost of the paint would be:
Cost of paint = Number of bottles of paint * Price per bottle of paint = x * $1.29
The cost of the canvases would be:
Cost of canvases = Number of canvases * Price per canvas = (x + 8) * $1.89
The total cost is the sum of the costs of paint and canvases:
Total cost = Cost of paint + Cost of canvases
we can write the equation:
Total cost = x * $1.29 + (x + 8) * $1.89 = $37.38
solve for x:
1.29x + 1.89(x + 8) = 37.38
1.29x + 1.89x + 15.12 = 37.38
3.18x + 15.12 = 37.38
3.18x = 22.26
x = 22.26 / 3.18
x ≈ 7
Therefore , she is buying approximately 7 bottles of paint and 7 + 8 = 15 canvases.

A ride at a carnival has two types of cars for children to ride. One type has 2 seats and one has 4 seats. There are 25 cars, and they can seat a total of 70 children. How many 4-seated cars are there?
There are 10 4-seated cars at the carnival.
Explanation:We are given that there are two types of cars at the carnival, one with 2 seats and one with 4 seats. We also know that there are a total of 25 cars and they can seat 70 children in total.
Let's assume the number of 2-seated cars is x and the number of 4-seated cars is y. We can set up a system of equations to represent the given information:
x + y = 25 (equation 1)2x + 4y = 70 (equation 2)We can solve this system of equations using substitution or elimination method. Let's solve it using elimination method:
Multiply equation 1 by 2 to make the coefficients of x the same: 2(x + y) = 2(25) --> 2x + 2y = 50 (equation 3)Subtract equation 3 from equation 2 to eliminate x: 2x + 4y - (2x + 2y) = 70 - 50 --> 2y = 20Divide both sides of the equation by 2 to solve for y: y = 10So, there are 10 4-seated cars at the carnival.

The carnival ride question can be solved using a system of equations with two variables representing the number of 2-seated and 4-seated cars. After setting up and solving the equations, we find there are 10 4-seated cars and 15 2-seated cars.
To tackle this problem, we need to set up two equations based on the seats and cars information given. Let's define x as the number of 2-seated cars and y as the number of 4-seated cars. The problem states that there are a total of 25 cars, which gives us the equation:
x + y = 25
Furthermore, we know that the total number of seats across all cars is 70. Since 2-seated cars contribute 2x to the total number of seats and 4-seated cars contribute 4y, we have the second equation:
2x + 4y = 70
To solve for y, we can manipulate these equations using substitution or elimination. For this example, let's use elimination. Divide the second equation by 2 to simplify it:
x + 2y = 35
Now subtract the first equation from this simplified second equation:
y = 35 - 25
y = 10
So, there are 10 4-seated cars. To find the number of 2-seated cars (x), substitute y back into the first equation:
x + 10 = 25
x = 25 - 10
x = 15
Thus, there are 15 2-seated cars.

alisa wrote a comparison for set b using the ten thousands place. Explain what strategy she could have used
Answer:
1000 to the 10 th power
Step-by-step explanation:
Just put it into power form
Since Alisa wrote a comparison for set b using the ten thousands place. The strategy that she could have used is 1000¹⁰
So, Alisa's strategy for comparing numbers in Set B using the ten thousand place involves focusing on a specific digit position to simplify the comparison process.
What is the comparisonIn Set B, the numbers are 492,111 and 409,867. By looking at the ten thousand place, which is the fourth digit from the right, Alisa can break down the comparison to:
492,111: The digit in the ten thousand place is 2.409,867: The digit in the ten thousand place is 0.Since 2 is greater than 0, Alisa can quickly deduce that 492,111 is larger than 409,867. This strategy is based on the idea that when numbers are similar in size, comparing them digit by digit can help us easily figure out which one is bigger.

Can the absolute value of an inequality be more than a negative?
Example:
4 |x-6| ≥ -8
Answer:
Yes, it would be all real numbers. If a negative was more than the absolute vaule, it would be false
Step-by-step explanation:
|x-6|>-2
pos. neg.
The the absolute vaule is ALWAYS positive so like I said before if the sign was facing towards the -2 it would be false
4 |x-6| (greater than or equal to)> -8
First you have to divide 4 on both sides since its outside the absolute vaule
then you will be left with
|x-6|>-2
since the 2 is a negative, you may think that this is automatically no solution, but sadly it isn't.
since the sign says the pos. sign is greater the equation is true and "all real numbers"

it takes 3/7 of an hour to paint 3/5 of room, how long does it take to paint one room?
Answer: [tex]\dfrac{5}{7}[/tex] of an hour
Step-by-step explanation:
Given : It takes [tex]\dfrac{3}{7}[/tex] of an hour to paint [tex]\dfrac{3}{5}[/tex] of a room.
i.e. Time taken to paint [tex]\dfrac{3}{5}[/tex] of a room.= [tex]\dfrac{3}{7}[/tex] of an hour.
Using Unitary Method, we have
Time taken to paint one room.= [tex]\dfrac{3}{7}\times\dfrac{5}{3}[/tex] of an hour.
⇒Time taken to paint one room=[tex]\dfrac{5}{7}[/tex] of an hour.
Hence, it will take [tex]\dfrac{5}{7}[/tex] of an hour to paint one room.
To paint one full room, it takes approximately 5/7 of an hour based on the given information that it takes 3/7 of an hour to paint 3/5 of a room.
Given that,
It takes 3/7 of an hour to paint 3/5 of a room.
The task is to determine how long it takes to paint one full room.
To find out how long it takes to paint one full room,
First, calculate the amount of time required to paint one-fifth of a room. Since it takes 3/7 of an hour to paint 3/5 of a room,
Set up a proportion:
(3/7 hour) / (3/5 room) = (x hour) / (1 room)
By cross-multiplying, we get:
(3/7) (1 room) = (3/5) (x hour)
Simplifying further, we have:
3/7 = (3/5) * (x hour)
To isolate x, we divide both sides of the equation by (3/5):
(3/7) / (3/5) = x hour
This simplifies to:
(3/7) * (5/3) = x hour
15/21 = x hour
x = 5/7 hour
Therefore, it takes 5/7 of an hour to paint one full room.
