Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?

Kylie is 24 years old

Step-by-step explanation:

kylie = x

Bobby=x-5

x+x-5=43

2x-5=43

2x=43+5

2x=48

X=24 years old

19

If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

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

the answer to the expression is 83
