Answer: the father is 44 years old now
Step-by-step explanation:
Let Bob's present age be represented by x
Let his father's present age be represented by y
Bob's age is 15 years less than half his father's age. This means that
x = y/2 - 15
x + 15 = y/2
y = 2x + 30
y - 2x = 30 - - - - - - - - - -1
In six years his father's age will be eleven years more than triple Bob's age. This means that
y + 6 = 3(x + 6) + 11
y + 6 = 3x + 18 + 11
y - 3x = 18 + 11 - 6
y - 3x = 18 + 11 - 6
y - 3x = 23 - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
x = 7
y = 2x + 30
y = 2×7 + 30
y = 14 + 30
y = 44
Answer:
A jar contains 5 red, 4 blue, and 3 yellow marbles.
The probability of pulling a red marble, then pulling a blue marble, without replacement would be:
P = 5/(5+4+3) x 4/(5+4+3-1) = 5/12 x 4/11 = 0.15 = ~0.2
Hope this helps!

Hi there!
81x - 122 = 22
Add 122 to both sides
81x = 144
Divide 81 from both sides
x = 144/81
Simplify
x = 16/9 or 1.78

Sally have deducted $103.78 from each paycheck.
Given,
Sally's employer pays 38% of her annual health premium of $4,350.
So, Sally's employer pay to his health premium will be,
