Answer:
30 minutes.
Step-by-step explanation:
You can make a proportion, which would be 10 selfies : 12 minutes. The second one will be 25 selfies : x minutes.
They have to be equal, since it is given that the rate stays the same. So 10:12=25:x
A proportion can be written as a fraction, so 10/12=25/x.
Cross multiply, and you get 10*x=12*25, or 10x=300.
Now divide both sides by 10 to get x=30.
she would have taken 20 selfies because 2 x 12 = 24 selfies, but there's still another minute.
she just took 24 selfies so how many would she take within a minute.
your answer is C.
y-27≥-13
+27 +27
y≥14
