Try using Symbolab, I use it all the time it gives the correct answer and it gives good explanations.
Dividing by a half is the same as multiplying by two. 3/4 multiplied by 2 is
or, in improper fraction form
or, in decimal form, 1.5
<span>The given function is f(x) = (7x + 1)/2. Write it as y = (7x)/2 + 1/2. To determine the inverse do these 3 steps. Step 1: Swap x and y to obtain x = (7y)/2 + 1/2. Step2: Solve for y. First, multiply through by 2 to obtain 2x = 7y + 1. Second, subtract 1 from each side to ontain 2x - 1 = 7y. Third, divide through by 7 to obtain (2x - 1)/7 = y. Step 3: Set y to the inverse of f(x) to obtain f^(-1) (x) = (2x - 1)/7.</span>

Answer:
197 students (rounded to the nearest whole number)
Step-by-step explanation:
first I divided 11 by 114 to find out how much girls there are to every one boy and my answer was 10.36 (rounded to the nearest 2 d.p).
next I times it by eight according to the ratio given, my answer was 83 (rounded to the nearest whole number)
finally, I just added 114 and 83 together to get the total number of students and my answer to that was 197 (rounded to the nearest whole number)
