We know that there are 15 children altogether
We know that the number that voted for B+R is double the number of students voted for G+Y
B+R = 2(G+Y)
Think of two numbers that add up to 15, one number is twice of the other number.
For example, 6 and 12.
12 is double of 6 but 6 + 12 doesn't give 15
So, think again
for example 5 and 10
10 is double of 5 and 5+10 does give 15
So, the number that voted Red and Blue is 10 and the number that voted Yellow and Green is 5
Answer:
1/3
Step-by-step explanation:
9:6
3:2
9/3 = 3
6/2 = 3

6 x (1/3) = 2
scale factor is 1/3
Answer:
Step-by-step explanation:
9 padlocks cost $25.20
Let the cost of a padlock be x
Then
- 9*x = 25.20
- x = 25.20/9
- x = $2.8
A padlock costs $2.8
Answer : 50 degrees
Explanation : Every triangle equals a total of 180 degrees. Use this fact to create an equation to solve for x. Add all expressions together.
You would get the equation 3 1/3x = 300
x = 90
Then plug x into the equation x - 40 to find the angle of A. This gives you 50.
