Question

At the market you purchase some apples and oranges. There were 12 items purchased. You buy twice as many apples as oranges.

a. Define the variables.

b. Write an algebraic equation using one variable for the above situation.

c. Solve this equation for the number of apples and oranges you purchase

Answer 1

variables are what u want them to be a believe

Answer 2

so x stands for oranges and y stands for apples

Answer 3

A. ) a = apples and o = oranges (be careful..that is o not a zero)

B) a = 2o
2o + o = 12 <-- your equation with 1 variable

C) 2o + o = 12
3o = 12
o = 12/3
o = 4

a + o = 12
a + 4 = 12
a = 12 - 4
a = 8

check..
2o + o = 12
2(4) + 4 = 12
8 + 4 = 12
12 = 12 (correct)

there are L 4 oranges and 8 apples

Answer 4

u would get y+X+X =12
