the gender of the kids does not matter so it can be discarded.
you add up how many boys and girls in the class to make a total of 50 kids
your 100% is 50
meaning 40% of 50 is 20
so if 20 kids took the bus to school then 30 did not take the bus.

Answer:
503
Step-by-step explanation:
For an arithmetic sequence, the n-th term is found by

To find
(the common difference) we can simply subtract one of the terms by the last, for example:

The common difference must be the same throughout the entire sequence, so we can do it once more just to be sure:

We also have to know that
stands for the first term of the sequence, which in this case is 311.
Now that we know this, let's find the 32nd term

Good luck!
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
4(x−7)=2(x+3)
Simplify both sides of the equation.
4(x−7)=2(x+3)
4x+−28=2x+6
4x−28=2x+6
Subtract 2x from both sides.
4x−28−2x=2x+6−2x
x−28=6
Add 28 to both sides.
2x−28+28=6+28
2x=34
Divide both sides by 2.
2x/2 = 34/2
x = 17
