Harini has twice as many sweet as Dora. After eating 18 sweets each she has 5 times as much as Dora. How many sweets did Harini start with?

9514 1404 393

  48

Step-by-step explanation:

Let d represent the number of sweets Dora has to start with. Then 2d is the number Harini had. After they each ate 18, the ratio of their numbers is ...

  (2d -18)/(d -18) = 5/1

  2d -18 = 5(d -18) . . . . . multiply by d-18

  72 = 3d . . . . . . . . . . subtract 2d-90

  24 = d . . . . . . . . . divide by 3

  2d = 48

Harini started with 48 sweets.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
