Answer:
15x2=30 combinations
Or x= activities a day
Y=crafts and sports
D=combinations
XxY=D
Step-by-step explanation: variables would be the activities per day and options of what to do. Multiply those to end up with the total number of combinations.
Answer:
The last 15 percent of that would be 39

Step-by-step explanation:
Answer:
x = 7/3
y = 1/3
Step-by-step explanation:
y = x - 2.... (1)
2x + y = 5.... (2)
Rearranging equation (2), we have
y = -2x +5 .... (3)
Let's multiply equation (1) by 2 so that we can easily simplify by substitution.
Therefore, it becomes 2y = 2x - 4 ... (4)
We add equation (3) and (4)
3y = 1
y= 1/3
Now, substitute (y= 1/3) in equation 1
It becomes:
1/3 = x - 2
x = 1/3 + 2
Simplifying with a LCM of 3
x = (1 plus 6, all over 3)
= 1+6/ 3
= 7/3
5 ≥ 2, so the second rule of <em>C(x)</em> applies :
<em>C</em> (5) = 25 + 3•(5 - 2) = 25 + 3•3 = 25 + 9 = 34
