Answer:
Step-by-step explanation:
since they are both equal to 'y', you can eliminate the y but letting the value of y equal to each other
if they are not both equal to 'y', then solve the equation by putting y itself on 1 side
1. sub y=-2x into 2nd equation
-2x = 3x + 25
then solve for x
-5x = 25
x= -5
2.
y-2 =12x
y = 12x +2
(sub this equation into y=x+2)
12x + 2 = x + 2
11x = 4
x = 4/11
hope this makes sense, please let me know if it doesn't and i'll help out some more
i'm not that great at explaining, sorry
Answer:
8.33%
Step-by-step explanation:
Given that the quiz has;
A multiple-choice question with 3 possible answers
A multiple-choice question with 4 possible answers
In the first question;
⇒The three choices,each has the probability of 1/3 to be picked
In the second question;
⇒The four choices, each has a probability of 1/4 to be picked
1/4
Finding the probability that both responses are correct will be;
1/3* 1/4 =1/12
As a percentage will be
1/12 * 100= 8.33%
I believe it would be 6 due to the radius being a half of the actual circumfrence
Answer:
9
Step-by-step explanation:
9
20 divided by 12 would be 12 and 4 for the greatest common factor so in simplistic form you would get 1 2/3. I hope I got the answer correct.....
