200/233=x/100
233x=20,000
20,000/233=85.8369
85.8369-100=-14.163%
Meaning there was a 14.163 percent decrease.

Answer:
And that's different from the claim of the student that:
The error of the student is that he/she changes the sign of the inequality from 
to 
and that's not possible since we don't multiply both sides of the equation by -1
Step-by-step explanation:
For this case we have the following inequality:
We want to rewrite the last expression with y in the left and x in the right so we can begin adding 3 in both sides of the inequality and we got:
Now we can divide both sides of the inequality by 2 and we got:
And that's different from the claim of the student that:
The error of the student is that he/she changes the sign of the inequality from to and that's not possible since we don't multiply both sides of the equation by -1
Answer:
100°
Step-by-step explanation:
The ratio of angles of the triangle is 2:2:5. We know that the angle sum property of the triangle is 180°. So that , let the ratio be 2x : 2x : 5x .
=> 2x + 2x + 5x = 180°
=> 9x = 180°
=> x = 180°/9
=> x = 20°
Here the largest ratio is 5x . Therefore the largest Angle is ,
=> Largest Angle = 5x
=> Largest Angle = 5 × 20°
=> Largest Angle = 100°
<h3>
• Hence the largest Angle is 100° </h3>
