Hello,

If 3x-1>=0 then

x>=1/3
|3x-1\=3x-1
2*|3x-1|=18
2*(3x-1)=18
6x-2=18
6x=20
x=10/3

else
x<1/3
|3x-1|=-(3x-1)
2*|3x-1|=18
2(-(3x-1))=18
-6x+2=18
-6x=16
x=-8/3
endif

Riverside Elementary School is holding a school-wide election to choose a school color. Five-eighths of the votes were for blue,
Mnenie [13.5K]

Answer:

Step-by-step explanation:

Let the total number of votes to choose a color = x

Number of votes for blue = \frac{5}{8}\times x

Remaining votes = x - \frac{5}{8}\times x

                            = \frac{8x-5x}{8}\times x

                            = \frac{3}{8}\times x

Votes for green = \frac{5}{9}\times (\text{Remaining votes})}

                          = \frac{5}{9}\times \frac{3x}{8}

                          = \frac{5}{24}\times x

Finally remaining votes = \frac{3x}{8}-\frac{5x}{24}

                                       = \frac{9x-5x}{24}

                                       = \frac{4x}{24}

                                       = \frac{x}{6}

Since these votes are for red therefore,

\frac{x}{6} = 48

x = 48×6

  = 288

a) Votes for blue are \frac{5x}{8}

Therefore, exact number for blue votes = \frac{5\times 288}{8}

= 5×36

= 180

b). Votes for green = \frac{5x}{24}

= \frac{5\times 288}{24}

= 60

c). Since 25 students were absent on that day of the vote, number of students at Riverside Elementary School = 288 + 25

= 313

d). Since seven tenths of the votes for blue were made by the girls.

Therefore, number of girls voted for blue = \frac{7}{10}\times 180

= 7×18

= 126

Since total votes made = 288

Therefore, half of the votes made = \frac{288}{2}

= 144

Now it's clear that number of votes made by girls is less than half of all the votes.

e). 126 girls voted for blue.
