Answer:
12 years
Step-by-step explanation:
Represent the mother's age by m and the son's by 4. Currently m = 36 years old.
In x years the mother will be three times as old as her son:
mother: 36 + x years old
son: 4 + x years old
The pertinent equation to solve is:
36 + x = 3(4 + x)
Performing the multiplication, we get:
36 + x = 12 + 3x, or
24 = 2x. Then x = 12.
Check: In 12 years, will the mother's age be 3 times the son's age?
Does 36 + 12 = 3(4 + 12)?
Does 48 = 48? YES
The mother will be 3 times as old as her son in 12 years from now.
Answer:
x-int=-8, y-int=2,-4
Step-by-step explanation:
for the x-int
you set x to 0 then solve the equation to get -8
for the y-int
you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4

Remark
You better be issuing a very small number of tickets.
Tickets vowels: a e i o u
Primes < 10: 2 3 5 7
Probability(e and 5) = 1/5 * 1/4 = 1/20
Answer: 1/20
Answer:0.05
You should probabily give 0.05 as your answer.
Answer:
51.36=38
Step-by-step explanation:
You apply all these together:
64-31-3.64 + 22=51.36
51.36=38
Answer: 40 minutes
Step-by-step explanation:
It takes 16 minutes for the first 2 stations to water their sections which means that the time taken per station is:
= 16/2
= 8 minutes per station
Ms. Reynolds has 5 stations.
Total time taken will therefore be:
= 8 * 5
= 40 minutes
