Hi!
Xian - 60 stamps
Kai - 76 stamps
60 + 12 = 72
76 + 8 = 84
72 + 12 = 84
84 + 8 = 92
84 + 12 = 96
92 + 8 = 100
96 + 12 = 108
100 + 8 = 108
After how many months will Xian and Kai have the same number of stamps?
4 months
How many stamps will each have?
108 stamps
Answer:
The number is = 16
Step-by-step explanation:
Given:
Twice the sum of a number and 2 is equal to three times the difference of the number and 4.
To find the number.
Solution:
Let the number be = 
The equation can be now written as:
Solving for
Using distribution:
Adding 12 both sides.
subtracting 
from both sides.
∴ 
Thus, the number is = 16
Answer:
x=3
Step-by-step explanation:

Answer:
0.006
Step-by-step explanation:
On the first draw, there are 52 cards, 4 of which are sevens.
On the second draw, there are 51 cards, 4 of which are nines.
The probability is:
(4/52) × (4/51)
= 4/663
≈ 0.006
Answer:
a. The slope is 5/4
b. The equation in slope and intercept form is y = 5/4·x + 12
c. The base cost of making a fruit juice is $12
Step-by-step explanation:
The equation that gives the cost in dollars of making your own fruit juice is given as follows;
y - 2 = 5/4·(x + 8)
a. The slope = The coefficient of x = 5/4
The slope = 5/4
b. The equation can be presented in slope and intercept form, y = m·x + c, as follows;
y - 2 = 5/4·(x + 8)
y = 5/4·x + 10 + 2
y = 5/4·x + 12
c. The base cost of making a fruit juice = The cost added to any quantity of fruit, x made = The y-intercept, c = 12
The base cost of making a fruit juice = $12.
