Answer: Im 90% sure its the first one
it might be wrong
Step-by-step explanation:
coreect me if im wrong:)
brainltist plz if correct xoxo kisses and hugs:)
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!
The answer is 13. The work is below
-4x/5≥1/10
-8x≥1
x≤-1/8
x∈(-∞;-1/8]
Answer:
x = P/8
Step-by-step explanation:
The perimeter of the blueprint is given by the equation :
P = 8x
We need to solve the above equation for x.
Dividing both sides of the equation by 8.

Hence, the value of x is P/8
