Answer:
0.2
Step-by-step explanation:
We have,
Number of blue tiles = 2
Number of red tiles = 3
Number of yellow tiles = 5
Total number of tiles = 2 + 3 + 5 is 10
Now, the probability of picking a blue tile is:
The number of blue tiles divided by the total number of tiles:
2 ÷ 10 = 0.2
Because you can't solve for two variables at once, you can guess and trial/error.
You can also give x or y any value, and then solve for the opposite variable.
x = 0
y = -36
for example. There are more solutions.
y + 8 = -4(x+7)
-36 + 8 = -4(0+7)
-28 = 0 - 28
-28 = -28
Answer:
1/3 + 3/8 = 17/24
Step-by-step explanation:
LCD is 24
3*8 = 24
8*3 = 24
3/24 + 9/24 = 17/24
14/3
28/6
56/12
there ya go. =)
