Answer:
She bought 16
Step-by-step explanation:
0.72*16=11.52
Make use of prime factorizations:

Both terms have a common factor of
:

- - -
The second one is not true! We can write

Both terms have a common factor of
:

Since
, and
, we'd still have to show that
is a multiple of 6. This is impossible, because
and there is no multiple of 2 that can be factored out.
if we look at the equation y = -2x - 1, is already in slope-intercept form, therefore,
has a slope of -2.
now, parallel lines have exactly equal slopes, therefore a parallel to that one above, will have also a slope of -2, so we're really looking for a line whose slope is -2 and runs through -1, 7.
