Answer:
1/6
Step-by-step explanation:
Probability = number of ways it could happen / total number of outcomes
Since there are 2 people with brown eyes, so the numerator is 2.
Since there are 12 people in total, the denominator is 12.
Probability = 2/12 = 1/6
If you mean <span>2x3(5x3 − 7)
2x3(15-7)
2x3(8)
6(8)
48
if you mean 2x^3(5x^3-7)
</span>2x^3(5x^3) - 2x^3(7)
10x^6-14x^3
replace the 1st equation into the 2nd one for y
-8x-4(2x-5) = -20
-8x-8x+20 =-20
-16x+20 = -40
-16x=-40
x = 5/2 = 2.5
y = 2x-5 - 2(2.5) - 5 = 5-5 = 0
one solution (2.5,0)
Answer:
The exact same as subtracting.
Example
5 + (-2) = 3
