But how many laps did she walk
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
Answer:
6x = 12
Step-by-step explanation:
2x + 3y - 10 = 0
4x - 3y - 2 = 0
add the two equations
2x + 3y - 10 = 0
4x - 3y - 2 = 0
--------------------
6x -12 = 0
add 12 to each side
6x -12 +12 = 0+12
6x =12
divide by 6
6x/6 =12/6
x =2
No, 45/85 does not simplify to 9/15
9*5=45
but 15* 5=75 not 85
