(3x + 1/2 ) + ( 7x - 4 1/2 )
3x+7x + 1/2 - 4 1/2
10x -4
It is not possible to draw here. I am attaching the diagram along with the answer. I hope the diagram will be clear for you to understand. I also hope that this is the answer that has actually come to your desired help. You can draw it with pencil, if you want to make it perfect.
Your answer would be 1/8.
The probability for getting a tail one time would be 1/2 because there are only 2 sides of a coin. Since tossing one coin doesn't affect the outcome of tossing the other coins, the probability for getting a tail on all of the coins is 1/2 each. We want this to happen 3 times, so the answer would be 1/2 × 1/2 × 1/2 = 1/8.
I hope this helps!
Answer:
x=21/40
Step-by-step explanation:
First get common denominators
3/8 *5 to top and bottom is now 15/40
3/20 *2 to top and bottom is now 6/40
isolate the X
x-15/40=6/40
+15/40 +15/40
x=21/40
