Answer:

<em>312 students </em>

Step-by-step explanation:

---- If 2 : 3 is a ratio of "in favour" vs "against to" then

\frac{2}{3} = \frac{x}{780-x}

3x = 2(780 - x)

3x + 2x = 1560

<em>x = 312</em>

If you recieved a score of 80% on an assignment, what is the ratio of correct answers to incorrect anwers?
ra1l [238]
Let's assume, for simplicity, that there were 100 questions in the test: a score of 80% means you got 80 right and (100-80)=20 wrong.

The ratio is then 80 to 20 or

80:20.

you can also simplyfy it, by dividing both numbers by 20:

4:1

which I think is the best way to give the answer!

Please help I’m struggling
gulaghasi [49]

Answer: B, x=20; angle measure is 30°.

Step-by-step explanation:

Opposite angles are always the same.

You can see that 30° and 3x are opposite angles therefore 3x=30°.

In algebra, when a letter and a number are next to each other, it means times.

So, 3x=30° means 3 times something equals 30.

And we know that 3×10=30 so, x=10.

Hope this helps :)

Twice the difference of x and 5 is -33
Elden [556K]
2*(x-5) = -33, so x-5 = -16.5, so x = -11.5

This is assuming that "the difference between a and b" is a-b, which seems to be the accepted interpretation.
