Answer:
9.) I 5/14 * 4/13 10.) H 45
Step-by-step explanation:
For 9.) the probability the first time to get a red marble is 5/14 because there are 5 red marbles and 14 total marbles. The probability the second time she picks, if a green one was chosen, one is 4/13 because one green marble needs to be missing and because one marble is missing 14-1=13 so there are 13 total marbles. You would multiply the two probability (5/14 and 4/13) to find the probability of drawing two green marbles in a row
For 10.) I found that 2/5= .4 and 5/8= .625 so I multiplied both fractions by 200
.4 * 200= 80
.625 * 200= 125
These are the numbers of games both people won
Subtract the two and you get 125-80= 45 which is how many more games Tyrell would win.
7x+2y=3 | ×3
x-3y=30 | ×2
21x + 6y = 9
2x - 6y = 60 +
--------------------------
23x / = 69
x = 69:23
x = 3
7x + 2y = 3
21 + 2y = 3
2y = -18
y = -9
Answer:
x = 2.5
Step-by-step explanation:
In order to solve for x, we need to write an equation. This question gives us the angles of a triangle, so we can use this to write our equation. All angles of a triangle will always add to 180 degrees, therefore:
(12x+6) + 104 + 40 = 180
Now we can just take out the brackets, combine like terms and isolate and solve for x:
12x + 6 + 104 + 40 = 180
12x + 150 = 180
12x + 150 - 150 = 180 - 150
12x = 30
12x/12 = 30/12
x = 2.5
Hope this helped!
Answer:
-8+0
Step-by-step explanation:
Answer:
Believe it or not, it would be 60 degrees.
Step-by-step explanation:
Here, we are working with ALTERNATE INTERIOR ANGLES. Since we know the beam supports for the top and bottom are parallel, 1&2 will be the same angle measurement.
Here is a diagram of an example of alternate interior angles, where m1=m2.
