2(4x-3)-7(x+1) first distribute
8x-6-7x+7 then combine the x's
<u>x+13 </u>
You have to turn them in to the lowest common denominator
Ratio of girls to boys = 5/3
Number of girls in 40 students would be 3/5 * 40 = 24
Answer:

Step-by-step explanation:
As we can see the given expression as three complex parts and all are being multiplied.
Lets simplify each part separately and then multiply all of them in the end
Part1
Cancelling 8 in numerator with 8 in denominator



Part2

simpliying



Part3
Third part is
, and it does not need to be further simplified
Now multiplying all the three parts





So our final answer is
