Answer: Third Choice. B,C, and E
Concept:
A scaled copy is a copy of a figure where every length in the original figure is multiplied by the same number.
Explanation:
Choice A. [tex]\boxed{FALSE}[/tex]
The figure given as choice A seems to be much thinner than the original image. Therefore, the figure did not copy each length in scale.
Choice B. [tex]\boxed{TRUE}[/tex]
The figure given as choice B seems to be the same size as the original image but different position. However, the position is not a concern in a scaled copy image. Therefore, the figure did copy each length in scale.
Choice C. [tex]\boxed{TRUE}[/tex]
The figure given as choice C seems to be larger than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.
Choice D. [tex]\boxed{FALSE}[/tex]
The figure given as choice D seems to be larger and wider than the original image. Therefore, the figure did not copy each length in scale.
Choice E. [tex]\boxed{TRUE}[/tex]
The figure given as choice E seems to be smaller than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.
Therefore, the choices would be B, C, E, which would be the third choice.
Extra: A shortcut (lazy) way to do the question
As listed above, A and D are clearly not to scale since one is much thinner, one is much wider. Therefore, we can directly neglect choices that contain A and D, which would only leave us with the third choice.
Hope this helps!! :)

Find the number that makes the ratio equivalent to 10:6.
Answer:
9*10=90 so 6*9=54 then answer is 90:54
Step-by-step explanation:
Select all ratios equivalent to 2:3.
Answer:
12:18 and 10:12 (i think)
Step-by-step explanation:
After converting the given ratios in their simplest form, the equivalent form of 2:3 we get 12:18.
To find the simplest form of a fraction, you have to simplify the numerator and denominator to their lowest terms and keep dividing until you can no longer simplify the fraction any further.
The given ratios are,
12:18,
3:21,
10:12
For the ratio 12:18,
Simplify it by finding the greatest common divisor (GCD) of 12 and 18.
The GCD of 12 and 18 is 6.
By dividing both numbers by 6, we get the smallest ratio of 2:3.
Moving to the ratio of 3:21,
Find the GCD of 3 and 21, which is 3.
Dividing both numbers by 3 results in the smallest ratio of 1:7.
Find the smallest ratio for 10:12.
The GCD of 10 and 12 is 2.
Dividing both numbers by 2 gives us the smallest ratio of 5:6.
Hence, the simplest form of ratios for the given ratios are:
12:18 = 2:3,
3:21 = 1:7,
10:12 = 5:6.
Hence,
The ratio equivalent to 2:3 is 12:18.

Jordan has to solve this division problem: 42 divided by 7 = ?
Which of the following equations can he use?
42 + 7 = ?
7 x 42 = ?
? x 7 = 42
7 divided by 42 = ?
The correct equation that Jordan can use to solve the division problem 42 divided by 7 is:
? x 7 = 42
So, the correct equation is option 3) ? x 7 = 42.
Given that, Jordan has to solve this division problem: 42 divided by 7 = ?
In this case, Jordan needs to find the value of the missing factor, which represents how many times 7 can be multiplied to get 42.
Therefore, he can use the equation:
? x 7 = 42
This equation represents the inverse operation of division, which is multiplication.
When we know one factor (7) and the product (42), we can use multiplication to find the missing factor (the quotient).
By solving for the missing factor, he will find the correct answer to the division problem:
The missing factor = 42 / 7 = 6
So, the correct equation is option 3) ? x 7 = 42.

6(9 + 5x) = 54 +
Hi
to progress in math, you must : know by heart the rules and formulas then train.
rule : a ( b+c ) = a*b + a*c.
this propertie is call distributivity .
so we have : 6 ( 9+5X)
here : a = 6
b = 9
c = 5X
so 6 ( 9+5X) = ?
I let you have a shot. Ask in comments section if you are stuck. But try first !
Answer:
1) rearrange terms:
6(9 + 5x) = 54
6(5x + 9) = 54
2) Distribution :
6(5x + 9) = 54
30x + 54= 54
3) subtract 54 from both side:
30x + 54 = 54
30x + 54 - 54 = 54 - 54
4) Simplify: subtract the numbers
30x = 0
5) Divide both side of the equation by the same term:
30x = 0
30x√30 = 0√30
6) Simplify: cancel term that are in the both numerator and denominator
x = O√30
solution :
x = 0]

1d) x = -4
----------------
2a) y = -3
2b) y = -60
2c) y = -83
2d) y = -50
Step-by-step explanation:
1a) y = x + 11
-30 = x + 11
-11 -11
------------------
-41 = x
1b) y = -2x - 32
-30 = -2x - 32
+32 +32
----------------------
2 = -2x
/-2 /-2
----------------------
-1 = x
1c) y = -3x - 1
-30 = -3x - 1
+1 +1
-----------------
-29 = -3x
/-3 /-3
------------------
29/3 = x
9.66 = x
1d) y = 5x - 10
-30 = 5x - 10
+10 +10
----------------------
-20 = 5x
/5 /5
----------------------
-4 = x
------------------------
2a) y = x + 3
y = -6 + 3
y = -3
2b) y = -2x - 72
y = -2(-6) - 72
y = 12 - 72
y = -60
2c) y = 3x - 65
y = 3(-6) - 65
y = -18 - 65
y = -83
2d) y = 4x - 26
y = 4(-6) - 26
y = -24 - 26
y = -50

Max makes three piles of cards, each consisting of only a Queen and a Jack. Lisa draws one card from each pile. What is the probability that Lisa draws two Queen and a Jack in any order? Make a tree diagram of all the choices
Answer:
3/8
Step-by-step explanation:
The probability of picking either a Queen or a Jack from each pile is always 1/2 (as there are only 2 cards).
There are only 3 ways in which Lisa can draw two Queens and a Jack:
Queen, Queen, Jack
Queen, Jack, Queen
Jack, Queen, Queen
The probability of each one happening is 1/8
This is because there is a 1/2 chance of picking a Queen or a Jack from each pile and to calculate the probability that Lisa will pick a Queen AND a Queen AND then a Jack (for example) you multiply the probabilities together:
1/2 x 1/2 x 1/2 = 1/8
This is the same for other examples and since there are only 3 ways that Lisa can draw two Queens and a Jack you multiply 1/8 by 3 (you add 1/8 together 3 times) to get 3/8
It can be represented on a tree diagram however I am not sure how I can show images/drawings on this

Which of the following equations is equivalent to
Answer:
Step-by-step explanation:
[tex]\frac{x+3}{3} =5- \frac{x-3}{6} \\(\frac{x+3}{3}) *6 =5 - (x-3)[/tex]
[tex]2x+6 = 5 - x+3[/tex]
Answer:
none
Step-by-step explanation:
We can start by multiplying both side of the equation by 6 in order to remove the fractions.
[tex]6*\frac{x+3}{3} = 6(5 - \frac{x-3}{6})[/tex]
[tex]2(x + 3) = 30 - 6*\frac{x-3}{6}[/tex]
[tex]2x + 6 = 30 -(x - 3)[/tex]
[tex]2x + 6 = 30 - x + 3[/tex]
Now, we can try to see if this equation is equivalent to the other options.
Every option has the left side as 2x - 6. In order to get that, we need to subtract 12 on both sides:
[tex]2x - 6 = 30 - x + 3 - 12[/tex]
This simplifies to
[tex]2x-6 = 18 - x + 3[/tex]
This is not the same as any of the options shown.
We can check this by solving the equations.
2x - 6 = 18 - x + 3
3x = 6 + 18 + 3
3x = 27
x = 9
Now, the first option:
2x - 6 = 10 - x - 3
3x = 6 + 10 - 3
3x = 13
x = 13/3
The second option is the exact same as the third, so they would have the same solution:
2x - 6 = 30 - x- 3
3x = 6 + 30 - 3
3x= 33
x = 11
Since none of the options have the answer 9, they are not equivalent to the equation shown.
