Answer:
12
Step-by-step explanation:
Since the entire line is 60 and MN is five times as long. Then I would say that you could just divide 60 by 1/5 or 0.2
Answer:
The only thing you will do is to plug the x in the equation.
x = -2 ---> f(x) = -6
x = 0 ---> f(x) = 0
x = 3 ---> f(x) = 9
x = 7 ---> f(x) = 21
f(x) = 3x
f(-2) = <u>3(-2)</u>
f(-2) = -6
f(0) = <u>3(0)</u>
f(0) = 0
f(3) = <u>3(3)</u>
f(3) = 9
21 = 3x
<u>21 / </u><u>3</u> = <u>3x / 3</u>
7 = x
Hope this helps, thank you :) !!
Answer:
P(1 and 2 are green) = 3/25
Step-by-step explanation:
We need to know the total number of marbles
6 Blue + 10 red + 9 green = 25 marbles
P ( 1st marble is green) = green/ total
= 9/25
Since we don't put it back, there are
6 Blue + 10 red + 8 green = 24 marbles
P ( 2st marble is green) = green/ total
= 8/24 = 1/3
P(1 and 2 are green) = P(1st green) * P(2nd green)
= 9/25 * 1/3
= 3/25
Answer:
2/3
Step-by-step explanation:
Simplify the following:
3/4 - 1/12
Put 3/4 - 1/12 over the common denominator 12. 3/4 - 1/12 = (3×3)/12 - 1/12:
(3×3)/12 - 1/12
3×3 = 9:
9/12 - 1/12
9/12 - 1/12 = (9 - 1)/12:
(9 - 1)/12
9 - 1 = 8:
8/12
The gcd of 8 and 12 is 4, so 8/12 = (4×2)/(4×3) = 4/4×2/3 = 2/3:
Answer: 2/3
Answer:

Step-by-step explanation:
I'm never sure how far to go on these questions but I think what I'e done looks pretty nice. Essentially I simplified each radical, factored out each variable, combined the radicals after more simplification, and then picked the answer you were most likely looking for. I gave some alternatives in my work that are "simple" too, but the answer above is most likely I'd say.
Work is in the attachment, comment with any questions.
