Y=10
Add 10 to both sides
-5y=-50
Then divide both sides by -5
y=10

Step-by-step explanation:
The ratio of Spanish students (S) to French students (F) is ...
S : F = 1.5 : 1
Multiplying that ratio by 2 gives ...
S : F = 3 : 2
This tells us there are 2 students taking French for every 3 taking Spanish.

<em>Comment on the problem statement</em>
Dragging students is a bad idea.
Let's set up a proportion.
Then solve for x:
12 x 800 = 9600
9600/100 = 96
96 is 12% of the 800 students. :)
Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)
Circumference of the outer circle = 2πr = 2π(6) = 12π
circumference of the outer arc = 120/360 x 12π = 12.57cm
circumference of the inner circle = 2πr = 2π(5) = 10π
circumference of the inner arc = 120/360 x 10π = 10.47 cm
Difference in length = 12.57 - 10.47 = 2.1cm (1 d.p.)
Answer: 2.1cm
