Ratios- coca cola has 65g sugars total. Equivalent amount of carrots: 1.383 kg or approx 3 lbs. so question asks
dimaraw [331]
This question means that Coca-Cola, which has 65 grams of sugar in a can (I assume), has the same sugar content as 1.383 kg of carrots. Coca-Cola is a distractor in this problem. (1.383kg/65g)=(1kg/s) Can you solve from there for s?

Solve: 5/2x - 1/3= -1/2<br><br>A. x=-5/12<br>B. x= -25/12<br>C. x= -1/15<br>D. x= 1/3​
devlian [24]

Answer:

c. x = -1/15

Step-by-step explanation:

5/2x - 1/3 = -1/2 [multiply the whole equation by 6 (lowest common denom)

15x - 2 = -3 [add 2 on both sides of equation

15x = -1 [divide both sides by 15 to isolate x]

x = -1/15
