he saves $75 for 8 months for a total of 75 x 8 = $600
he wants to save $900
so he needs 900 - 600 = 300 more.
this means he needs to save 300 / 2 months = $150 per month.
not sure if there're any answer choices of some sort,
but if the angle a and angle b are supplementary, that means when you add their measures together they must equal 180.
less than one
suppose that you have a pizza divided into some equal parts (in m parts). each of these parts is represented by a fraction () less than 1. if you want to share one part of this pizza between some friends (for example, between n friends), you should divide this part of pizza into equal number of parts (in n parts). what do each friend get? a part from a part. the quotient is less than one.
