First you find common denominator which is 18, you don't have to change 2/18
1x3=3
6x3=18
so 3/18 plus 2/18= 5/18
So your answer is 5/18
Answer:
512 ounces
Step-by-step explanation:
Both equations start with y =
Set both equations equal to each other and solve for x first:
1/3x-4 = -7/3x +4
Add 7/3x to both sides:
8/3x - 4 = 4
Add 4 to each side:
8/3x = 8
Divide both sides by 8/3
x = 3
Now you have the value of x, replace x in the equation to solve for y:
y = 1/3(3) -4 = 1-4 = -3
y = -7/3(3) +4 = -7+4 = -3
y = -3
X = 3 and y = -3
Answer:1/870
Step-by-step explanation:
The total number of student in Mr parietti class is 30 (18girls and 12boys). If a student is first chosen at random from the class. The probability of choosing 1 student out of 30 will be 1/30.
He then chose another student without replacing the first, the probability of choosing that second lady will be 1/29 (since the remaining students are 29).
the probability that both students chosen are girls will be 1/30×1/29 = 1/870
