Answer: The required ratio is 1:1.
Step-by-step explanation:
Let the total number of CDs be 100
of CDs is given by
According to question,
of her Jazz CDs represents of all her CDs.
Let the number of Jazz CDs be x
So, it becomes
So, Number of Jazz's CDs is 50
Number of Jazz non CDs is given by
Ratio of her CDs to her non- CDs is given by
Hence, the required ratio is 1:1.
I believe the answer is -2
Answer:
2x+7/6
Step-by-step explanation:
an normal function would be mapping x to y, since this is the inverse we would map y to x
f(x) and y are the same so I will take f(x) as "y"
1)3x-7/2=y
3y-7/2=x
solve/isolate "y" in 3y-7/2=x to get the value of "y"
3y-7/2=x
add "7/2" to both sides
3y-7/2+7/2=x+7/2
3y=x+7/2
divide both sides by "3"
3y/3=x/3+7/2/3
simplify:
y=2x+7/6
hope this helps!
Answer:
Angle1:12
Angle2:168
Step-by-step explanation:
Angle 1+angle 2=180
X-9+8x=180
9x=189
x=21
angle1=21-9=12
Angle2=180-12=168
