We take 2 marbles from 20 marbles and the total ways is 20x19:2=190
But we need only 2 red marbles and the ways is 14x13:2=91
And finally we do the division 91:190=91/190 is the probability we need
Answer:
y = -1x -4
Step-by-step explanation:
The point slope equation is y - y1 = m(x -x1).
You will have to plug in the points (-3, -1) and (2, -6).
y - (-1) = m (x - (-3))
To find "m", find y over x.
m = (y2 - y1) / ( x2 - x1)
m = (-6 + 1)/(2 + 3)
m = -5/5
m = -1
Then plug in "m"
y + 1 = -1(x + 3)
then distribute the "m" into the parenthesis and isolate y or subtract 1 from both sides.
y + 1 = -1x - 3
y = -1x -4
Hi there!
<u>Here are all the steps into solving this equation :</u>
<u>- 8</u> = 5.4
Add 8 on each side of the equation → 5.4 + 8 = 13.4
= 13.4
Multiply each side of the equation by 5 → 13.4 × 5 = 67
9z <u>+ 4</u> = 67
Subtract 4 from each side of the equation → 67 - 4 = 63
<u>9</u>z = 63
Divide each side of the equation by 9 → 63 ÷ 9 = 7
z = 7
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
233.35488 km (Rounded to 233 km)
Step-by-step explanation:
If you convert miles to kilometers then you would use this conversion factor:
1 mile = 1.609344 km (or 1.61 km)
so in this case,
145 mile = 1.609344 km x 145
145 mile = 233.35488 km
I could also round it to 233 km.
Since your on a trip... i hope u enjoy ur journey to Las Vegas!
answer:
the answer is -3 and 8
Step-by-step explanation:
we will place -3 in the equation
(x+3)(x-x)=0
(-3+3)=0 (because -3+3 will cut down together)
we will place two 8(eights) in the equation
(8-8)=0
final answer is
(0)(0)=0
so -3 and 8 fits well in the equation
