If you add or subtract by a number you must add the equality sign
If solving for x:
Because both equations are equal to Y, you can set both equations equal to each other:
5x+1=4x+8
Then it's a matter of simplification (subtract the 4x to the left side and subtract the 1 over to the right):
x=7
If solving for Y:
Plug x=7 into either equation and solve:
Y=4(7)+8
Y=36
Answer: 0.0546875
Step-by-step explanation:
The number of times the coin landing head 8 out of 10 is simply:
C(10, 8)/2^10. At least 8 means, 8 or more. Since the events here are dependent on themselves the answer would be:
[ C(10, 8) + C(10, 9) + C(10, 10) ] / 2^10 = 56/1024 = 0.0546875
Answer:
1/2
Step-by-step explanation:
first find the least. common multiple of the denominators(LCM)
this is 18
18
divide each denominator with the lcm
then multiply the answers you get by the numerators...
e.g2/3. 18÷3×2=12. 1/6. 18/6x1 which is 3
then 12-3 which is 9 over the lcm which is 18
the. simplified form of the answer is
1/2
