Answer:
Step-by-step explanation:
Let the x be the number of months.
In x months, xian will have:
(52+16x) stamps
and kai will have:
(76+12x)stamps
To find out how many months they will have the same number of stamps, we evaluate the two expressions:
52+16x=76+12x
52+4x=76
4x=24
x=6
So xian and kai will have the same number of stamps after 6 months.
Using either of two expressions, each will have:
52+16(6)=76+12(6)= 148 stamps.

The experimental probability in this problem is given by the total amount of silver coins Clarisse pulled over the total amount of coins Clarisse pulled.
She pulled 48 silver coins out of the 60 she pulled in total. Set up a fraction:
This fraction can be simplified by dividing both the numerator and denominator by 12:
The experimental probability of pulling another silver token is
4/5.
There's <u>24 possible outcomes</u>.
There's only 6 outcomes with the cube and 4 outcomes with the cards. Multiply 6 and 4 and you get 24.
The divisibility rule for 12: A number is divisible by 12 if it's divisible by both 6 and 2. The reason for this is because 12 = 6 x 2.
Answer:
Let the number of brownies made by Rachel and Trish be R and T respectively.
R+T= 84 ---------(1)
R= 5(12)= 60
Substitute into (1):
60 + T = 84
T= 84-60
T= 24
Therefore, number of pans of brownies made by Trish
= 24÷12
=2
Alternatively,
Let the number of pans of brownies made by Trish be x.
Total number of pans of brownies= 84/12= 7
Since Rachel contributed 5 pans,
x+5=7
x= 7-5= 2
Thus, Trish made 2 pans of brownies.
