Tia owns a fruit shop and is selling a fresh lot of apples and oranges. she wants the ratio of apples to oranges sold to be 4 to 2. tia wants to sell a total of 42 apples and oranges. how many apples should she sell?

28 apples

Step-by-step explanation:

Let

x> the number of apples

y > the number of oranges

we know that

x+y=42 > equation A

x/y=4/2 > x=2y > equation B

Solve the system of equations by substitution

substitute equation B in equation A and solve for y

2y+y=42

3y=42

y=42/3=14 oranges

Find the value of x

x=2y > x=2(14)=28 apples

the answer is c. 23/3

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
