-5x+7(-3x-14)=162 how do you solve?

x = -10

Step-by-step explanation

5x+7(-3x-14)=162

First, 5x -21x - 98 = 162

Then, combine like-terms, -26x - 98 = 162

After that, add 98 to 162, and you'll end up with 260.

Finally, you'll wanna divide the -26x to the 162.

You'll end up with x = -10

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
