Answer:
I think the answer is 11.8
Step-by-step explanation:
25+ [ 15- 4 x 16/5] - 15.4
25 +[ 15- 4/1 x 16/5] - 15.4
25+ [ 15 - 20/5 x 16/5] - 15.4
25 +[ 15 - 64/5] - 15.4
25+ [ 15/1 - 64/5] - 15.4
25+ [75/5 - 64/5] - 15.4
25+ 11/5 - 15.4
25+ 2.2 - 15.4
27.2 - 15.4
11.8
I think its 19. should be right
Answer:
no
Step-by-step explanation:
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!
It’s already in slope intercept form
