The points F, G, H and I all lie on the same line segment, in that order, such that the ratio of FG : GH: HI is equal to 3 : 2: 4. If FI = 18, find FH.

10

Step-by-step explanation:

    Given line:

              F       G       H        I

 FI  = 18

Unknown:

FH = ?

Solution:

To find the line FH, we use the ratio given;

               FG : GH: HI

               3    :   2  : 4 ; Total  = 3 + 2 + 4 = 9

  Since FI is 18;

FH  =  x 18 =  = 10

FH  = 10

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
