40% of 35 would be 14. Therefore 14 girls are in the class. Hope that helps!
Answer:
Number of sundaes = 36
Number of banana split = 28
Step-by-step explanation:
On that day, let the number of sundaes sold be x
Now, since they sold 8 more sundaes than banana, the number of bananas sold is x-8
So the cost of sundaes sold will be 2 * x = 2x
the total cost of banana splits sold will be 3(x-8) = 3x -24
The addition of both equals 156
Hence;
2x + 3x-24 = 156
5x -24 = 156
5x = 156 + 24
5x = 180
x = 180/5
x = 36
So
number of sundaes sold is 36 while the number of bananas split sold is 36-8 = 28

Kelly made a mistake by not following PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. She added 4 and 3 before multiplying it by two when the multiplication comes before the addition or subtraction. Brook is correct.
Answer:
x = 
Step-by-step explanation:
Data provided:
ln(x) − ln(y) = 2a
Now,
The using the following properties of log function,
we have
log(A) - log(B) = 
and,
ln(a) = b is equivalent to a =
(here e is exponential )
ln(e) = 1
therefore,
the above equation transforms as:
= 2a
taking anti-ln both sides,
we get
= 
or
x =
