Answer:
Explanation:
A fast way you can do it is just plug the choices and see which one equals to 16. So like this 1/2(16)+1/4(16)=16. This equals 12 so 16 is incorrect. Or write it like this 0.5(21.3)+0.25(21.3)=16. Writing it in decimal form would be much easier. So plug in the rest and see which one is equal to 16.
x = 64/3 ( in decimal form)
First, we're going to combine like terms:
We'll find the least common denominator of 2 and 4, which is 4. Now watch what happens
Multiply both sides by 4
Divide both sides by 3
