MaRussiya [10]

Answer: 245 cu. cm.

Step-by-step explanation:

4/7-2/5=20/35-14/35=6/35

42 cm3 represents 6/35 of the total volume

how many 6/35's are in 35/35 ? (the total volume)

(35/35)/(6/35)=(35/35)*(35/6)=35/6=5 5/6

(5 5/6)*(42)=(35/6)*(42)=35*7=245 cm3 is the total volume

Idk how to do this without an image honestly

Answer:

  (x, y) ⇒ (x -m, y -n)

Step-by-step explanation:

Reverse the arrow and solve for the x and y on the left:

  (x +m, y +n) ⇒ (x, y)

This resolves to two relations:

  x + m ⇒ x

  x ⇒ x - m . . . . . subtract m

and

  y + n ⇒ y

  y ⇒ y - n . . . . . . subtract n

Putting these back together, we have ...

  (x, y) ⇒ (x -m, y -n) . . . . . maps P'Q' to PQ

_____

The original translation was right m and up n. The reverse translation is left m and down n. That is what the rule shows.
