Dan and his mom went to the
supermarket. the total amount of
their purchase was $126.62. if
dan's mom hands the cashier
seven $20 bills, how much change
did his mom receive?

First, we must figure out how much money seven $20 bills are worth. We can multiply 20 by 7 and we will get a product of 140.

If Dan's mom gives the cashier $140, Dan's mom will receive change. We can find out how much change she is getting by subtracting 126.62 from 140.

$140 - $126.62 = $13.38

Therefore, Dan's mom will get $13.38 in change.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
