Step-by-step explanation:
- Create an equation to find y: 3 =
- Calculate by adding: 3 =
- Multiply both sides of the equation by 7 : 21 = y - 2
- Move the variable to the left-hand side and change its sign : -y + 21 = -2
- Calculate and change signs : y = 23
y = 23
Answer:
Step-by-step explanation:
Let the total number of votes to choose a color = x
Number of votes for blue =
Remaining votes = x -
=
=
Votes for green =
=
=
Finally remaining votes =
=
=
=
Since these votes are for red therefore,
= 48
x = 48×6
= 288
a) Votes for blue are
Therefore, exact number for blue votes =
= 5×36
= 180
b). Votes for green =
=
= 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 =
= 7×18
= 126
Since total votes made = 288
Therefore, half of the votes made =

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.
