1/2x + 3 = 2/3x + 1....multiply everything by the common denominator of 6
3x + 18 = 4x + 6
3x - 4x = 6 - 18
-x = - 12
x = 12 <====
multiplying by the common denominator will get rid of the fractions
If she rides at 12 miles per hour, we know that 45 minutes is three quarters of an hour, therefore just workout:
3/4 x 12 = 9
So she would travel 9 miles in 45 minutes.

Answer:
Maybe 12.56
Step-by-step explanation:
Well, the question is a bit hard to read, but I assume the radius is equal to 2?
The formula for the area of a circle is п*r*r
The number п is equal to 3.14
so п*2*2 = 3.14*4 = 12.56
Though if the radius is not 2, try to use that formula and if you cant get it please let me know in the comments
