Every month, omar buys pizzas to serve at a party for his friends. in may, he brought three more than twice the number of pizzas he bought in april. if omar bought 15 pizzas in may, how many pizzas did he buy in april

Step-by-step explanation:

Omar bought 15 pizzas in May.

In May, he bought 3 more than twice the number that he bought in April.

Since we don't know how many he bought in April, let X = the number of April pizzas.

Then, 15 = 2X + 3

Now you can subtract 3 from both sides, then divide both sides by 2 to leave X by itself and discover what it equals.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
