Elaine says, “To find 6 ➗ 2/3, I can just take the value of 6 ➗ 1/3 then either multiply it by 1/2 or divide it by 2.” Do you agree with her? Explain why or why not.
Answer:
I do not agree with her
Step-by-step explanation:
You can find the answer by doing the keep change flip method. So keep the 6, chnage the sign to a multiplication sign, then flip the 2/3 to 3/2. Then you multiply and you get 18/2 which simplifies to 9.

Sally and Marta had the same number of postcards. After Sally sold
18 of her postcards, Marta had 4 times as many postcards as Sally.
How many postcards did each girl have to begin with?
Answer:
the equation x - 18 = 4(x - 18)
Step-by-step explanation:
x - 18 = 4x - 72
x - 4x = - 72 + 18
- 3x = - 54
x = 54/3
x = 18
Sally had 36 postcards to begin with (18 + 18)
martha had 0 postcards to begin with
i feel like i did something wrong someone double check this but i think this is the answer.
Answer:
x-18 = 4(x-18)
Step-by-step explanation:
x-18 =4x-72
3x =54
x=54/3
x=27

Answer:
-14
Step-by-step explanation:
Answer:
-14, fourth choice
Step-by-step explanation:
absolute value is represented with this |x|, the 2 lines
The absolute value for a real number, in this case -14, is the non-negative value without regard to its sign. So the absolute value of -5 would be 5, and the absolute value of 7 would still be 7
In this case there's no 14, so u can choose -14

Answer:
-4x + 9xStep-by-step explanation:
Combine like terms:
-4x - 9x = (-4 - 9)x = -13x
4x - (-9x) = 4x + 9x = (4 + 9)x = 13x
-4x + 9x = (-4 + 9)x = 5x
4x - 9x = (4 - 9)x = -5x
Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.
Which rule best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH?
Option D is correct (x, y) → (2.5x, 2.5y).
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.
Since Scale factor:
A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
In our case,
A dilation of 2.5 because side AB is 4 units and EF is 10 units and if you divide 10/4 will get you with your scale factor.
thus, Scale factor is 2.5
Therefore, best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH is D. (x, y) → (2.5x, 2.5y)

Answer:
E. 18 children are buying their lunches
F. Rock must pay $50 each month
Step-by-step explanation:
E.
To find a percentage you multiply the number by the percentage;
60 x 70%(0.70) = 42 children brought their lunches
But we need the amount buying their lunches so we would subtract 60 by 42;
60 - 42 = 18 buying their lunches
F.
Again, to find the percentage we multiply it by the original;
$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa
Now we need to find how much Rock still needs to pay for the sofa;
$800 - $200 = $600 more needed to pay for the sofa
Lastly, we must find how much Rock will need to pay each month to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;
$600 / 12 = $50 needs to be paid each month for a year
