<span>one cubic foot is equal to (about) 7.5 gallons
</span>
Let
x----------> <span>Aidan's age
y----------> M</span><span>aggie's age
we know that
x=4
x=(y/2)-6
so
substitute
4=(y/2)-6----> multiply by 2-----> 8=y-12----> y=8+12-----> y=20
the answer is
</span>M<span>aggie's age is </span><span>20</span>
Im no expert but i think its
input: x,independent variable ,domain
output: y, dependent variable , range
extra: f(x) , discrete, and slope
Mean is the average
mode is most common number
we can do
hmm
average of 3 and 9 is 6
3,3,6,9,9 will work
we can make it vary slightly
2,4,6,9,9
mean is 6, mode is 9
