Susan has a mixture of $2 notes, $5 notes and $50 nots in her wallet. the sum of the number of $2 notes and $5 notes if thrice the number of $50 notes. a) let the number of $2 notes be x and the number of $5 notes be y. find an expression for the number of $50 notes.
b) the total amount of cash in her wallet is $301. show that 56x+65y=903
given that susan has one more $2 note than $5 note, find the value of x and y

The graph below shows the price of different numbers of mats at a store: a graph is shown. the values on the x axis are 0, 2, 4, 6, 8, 10. the values on the y axis are 0, 21, 42, 63, 84, and 105. points are shown on ordered pairs 0, 0 and 2, 21 and 4, 42 and 6, 63 and 8, 84. these points are connected by a line. the label on the x axis is number of mats. the title on the y axis is price in dollars. which equation can be used to determine p, the cost of b mats?

If f(x)= 3x+6 which of the following is the inverse of f(x)

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
