The first , second, and fourth options if you are on edge.
3 : 8....can be written as 3/8
12 lbs of apples were sold
apples / oranges : 3/8 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (12)(8)
3x = 96
x = 96/3
x = 32 <=== 32 lbs of oranges
notice that 3/8 = 12/32....these are equivalent fractions....because that is what proportions are, equivalent fractions
Hello!
<em><u>Answer:</u></em>
<em><u>d=3</u></em>
<em><u>*The answer must have a positive sign.*</u></em>
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, you multiply by 10 from both sides of an equation.

Then, you had to refine the problem down.

Next, you subtract by 54 from both sides of an equation.

Simplify.

You can also divide by 22 from both sides of an equation.

And finally, simplify and solve. You can also divide by the numbers.

Final answer: → 
Hope this helps!
Thanks!
