Four students were having a debate about how to handle order of operations problems. Genesis said that when you answer a question that has multiplication and division in it, you
always do the multiplication first because M comes before D in PEMDAS.
Aniyah said that when you answer a question that has multiplication and division in it, you
work on them from left to right.
Lauren said that when you answer a question that has multiplication and division in it, you
work on them from right to left because that's how she reads her favorite Manga books.
Ty said that when you answer a question that has multiplication and division in it, you
solve whichever part makes the problem easiest first.
Which student is correct? Explain your answer.

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

it shoild be o
