Answer:
f, s={36,6} is your answer.
Step-by-step explanation:
PREMISES
6s+9=3(s+9)
ASSUMPTIONS/SUFFICIENT CONDITION(S)
Let the son's current age s=s
Let the father's current age f=6s
CALCULATIONS
6s+9=3(s+9)
6s+9=3s+27
6s-3s+(9–9)=3s-3s+(27–9)
3s+0=0+18
3s=18
3s/3=18/3
s=
6
and,
if s=6, then
6s=
f=
36
PROOF
If f,s=36, 6, then the equations
6s+9=3(s+9)
6(6)+9=3(6+9)
36+9=3(15) and
45=45 establish the roots (zeros) f, s=36,6 of the mathematical statement 6s+9=3(s+9)
Nothing times itself will equal 29, but in decimal form only is 5.38
Answer:
It will be about 12 inches
Answer:
1/8
Step-by-step explanation:
The probability of getting tails on a single flip is 1/2.
Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.
So, your answer will look like this
x x ; which equals;
1/8
One dice has 6 sides and two dice will give us 12 sides with 36 possibilities
it will be 9/36=.25
so it will have 25% chance of the two dice to have a sum of 9
