Answer: x= -9/19
Step-by-step explanation:
5x+18/8=x/4
5x+ 9/4=x/4
5x+9/4-9/4=x/4-9/4
5x= x-9/4
5x(4)=x-9/4(4)
20x=x-9
20x-x=x-9-x
19x=-9
19x/19=-9/19
x=-9/19
3(10g + 6y)
3(10g) +3 (6y)
30g + 18y
option 2
The probability of finding 2 never married
10c2*0.4^2*0.6^8=
the probability of finding 1 never married
10C1*0.4*0.6^9=
the probability of finding 0 never married
10C0*0.6^10=
the answer is all the above answers added together.
think you can do the rest of the calculation by yourself. :)
btw nCr=n!/(n-r)!r!
good luck
Answer: (5,0)
Step-by-step explanation:
x - 3y =5 -----------(1)
2x + y = 10 ----------(2)
By elimination method, multiply eqn(1) by 2
2x - 6y = 10 ------------(3)
eqn(3) - eqn(2)
-7y = 0
Divide bothside by -7
y= 0
Now, we substitute the value of y in eqn(1)
x - 3(0) = 5
x - 0 = 5
x=5
Therefore,x=5 and y=0
