Alexus is modeling the growth of bacteria for an experiment in science. She assumes that there are 1,000 bacteria in a Petri dish at 12:00 noon. Create a table that shows the total number of bacteria in the Petri dish at 30 minutes intervals for 2 hours starting with time 0 to represent 12:00 noon
What is Time (minutes) 0 30 60 90 120 Number of bacteria 1,000 500 250 125 62.5

(2x+7) is equivalent to (2x + 3) + 4. What is the definition of equivalent expressions?
When two expressions are equivalent, assigning the same value to x in both expressions will give an equivalent numerical expression. Expressions can be changed using distributive, associative, and commutative properties.

A store sells Brazilian coffee for $10 per lb. and Columbian coffee for $14 per lb. The store decides to make a 150-lb. blend of the two and sell it for $11 per lb. Write a system of equations that can be used to find how much of each type of coffee should be used.
B + C = 150 10B + 14C= $1,650
