You have to think about what y and x can be equal to for you to get 12. (Hint: y is going to be a bigger number than x)
Ex: 3y-5x=5
Think: 3 x 10(y) - 5 x 5(x)= 5
So, y would be 10 and x would be 5.

Answer:
The probability that a person is younger than 50 given that she uses onling banking is 1.5%
Step-by-step explanation:
The survey indicated that 50% of adults conducts their banking online.
P(online banking customers) =1/2
Of the total number of customer that bank online, the survey stated that 20% of them are younger than 50 years.
P(customers younger than 50 yrs) =1/5
Out of the 20% than are younger than 50, we were told that 15% of them conduct online banking.
P(younger than 50 online banking customer) =3/20
Therefore the the probability that a = person is younger than 50 given that she uses online banking is P = 3/20*1/5*1/2 =17==3/200 = 0.015 =1.5%
The probability that she is younger than 50 does not increase or decrease with additional information, it only makes it clearer.
If v is cut in half, then w is multiplied by (1/(1/2))^2 = 4.
When v=3, w=12.
Answer:
Kirk wrapped 7 presents with those 23.8 cm of tape.
Step-by-step explanation:
Figure out the unit rate:
10.2 cm tape
-------------------
3 presents
or
3 presents
-----------------------
10.2 cm tape
Multiplying this by 23.8 cm results in the number of presents Kirk wrapped with that much tape:
(3 presents)(23.8 cm tape
--------------------------------------- = 7 presents
10.2 cm tape
Kirk wrapped 7 presents with those 23.8 cm of tape.
