Solve for x. −(−2−5x)+(−2)=18 a. x=−185 b. x=−90 c. x=90 d. x=185

The correct answer is none of the ones listed. The correct answer is 18/5.

In order to find this, follow the order of operations.

−(−2−5x)+(−2)=18 ---> Distribute the negative

2 + 5x - 2 = 18 > Combine like terms

5x = 18 > Divide by 5

x = 18/5

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

3xy cannot be combined with the others

2x, -5x and x are like terms
