1. The ratio of girls to boys to parents at the concert is 10:5:4. If there are 1083 people at the concert, how many parents are there?

2. Solve for x:

x - 107=x + 189

3. Solve for x:Follow steps: 1. Distribute 2. Anything not a fraction, put it over one 3. Find common denominators 4. Anything you do to the bottom, you must do to the
Top. 5. Eliminate denominators. 6. Solve

27(x - 2) + 5x = 12x - 9

4. Solve for x and state the solution(s).

-4(x - 8) - 3x = -7x + 32

1.   228 parents

Step-by-step explanation:

I will do number 1 for you.  I'll let you or someone else do the others.

Let 10x = no. of girls

      5x = no. of boys

      4x = no. of parents

Now, 10x + 5x + 4x = 1083

                        19x = 1083

                            x = 57

(10)(57) = 570 girls

(5)(57) = 285 boys

(4)(57) = 228 parents

             1083  total

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: the answer is ann
