fourth as many supreme pizzas as pepperoni, if he paid for 39 pizzas total, how many of each type of pizza did he order? (Write an equation or draw a diagram to support your
answer)

3. solve by graphing: y = 2x + 6 x + y = -3

Evaluate the expression for the given value of the variable 7a - 4a for a =8

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
