Answer:
32 CDs, 13 Videos
Step-by-step explanation:
You can represent this question using variables.
Let x = #CDs sold, Let y = #videos sold.
You can formula two equations with the information given:
3x + 7y = 187
x + y = 45
Substitute x into the equation above by reducing the equation below:
x + y = 45 -> x = 45 -y
Since we are now able to remove x from the equation, plug in your new value into the equation above.
3(45-y) + 7y =187
135 - 3y +7y = 187
135 + 4y = 187
4y = 52
y = 13
Knowing the value of y, simply plug in this y value to solve for x:
x + 13 = 45
x = 32
Answer:
9/17 are even and 9/17=.52 There is a 52% chance it will be even.
Step-by-step explanation:
1+1=2 1+2=3 1+3=4 1+4=5 1+5=6 1+6=7 (3 out of 6 are even)
2+2=4 2+3=5 2+4=6 2+5=7 2+6=8 (3 out of 5 are even)
3+3=6 3+4=7 3+5=8 3+6=9 (2 out of 4 are even)
4+5=9 4+6=10 (1 out of 2 are even)
5+6=11
