Answer:
17 boys and 11 girls
Step-by-step explanation:
Create a system of equations where b is the number of boys and g is the number of girls:
b + g = 28
b = g + 6
Solve by substitution, by substituting the second equation into the first one:
b + g = 28
(g + 6) + g = 28
2g + 6 = 28
2g = 22
g = 11
So, there are 11 girls.
Since there are 6 more boys than girls, there are 17 boys.
So, there are 17 boys and 11 girls in the class.

The winning time increased by an average of 0.4 second per year from year 2 to year 4.
Step-by-step explanation:
I just took the quiz
9(6+x)
by the distributive property,
distributing the 9 to each term in the brackets,
we get,
9*6 + 9*x
So yes, #1 is true.
---------------------------------------------------------------
(x+8)9
again by the distributive property,
giving the 9 to each term in the brackets,
x*9 + 8*9
which is NOT the same as
x + (8*9)
so #2 is false.
Hope that helps.
