Solve the equation: 1/2x-5+2/3x=7\6+4

Step-by-step explanation:

=1/2x - 5 + 2/3x = 7/6 + 4

(1/2 and 2/3 are like terms so we can add them. Next we have to find the lcm)

= lcm is 6 so now we make the denominators same and add them up

= 3+4/6x - 5 = 7/6 + 4

= 7/6x - 5 = 7/6 + 4

Now we do the same to the other side- find lcm and add them

= 7/6x - 5 = 14+48/ 12

= 7/6x -5 = 62/12

Now we bring 5 from the left to the right

= 7/6x = 62/12 + 5

Now we find the lcm again and add them

= 7/6x = 62+60/12

= 7/6x= 122/12

Now we bring the number in the lhs to rhs

= x= 122/12 divided by. 6/7

= x = 122/12 multiplied by 7/6

= x= 11.86

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
