Answer:
3(x+4)−x>4
(3x+3·4)−x>4
(3x+12)−x>4
3x+12−x>4
3x−x+12>4
2x+12>4
(2x+12)+(−12)>4+(−12)
2x+12−12>4−12

Answer:
Answer A. 30 I believe.
Step-by-step explanation:
You can use proportions.
Milk:
6 is to 2 2/3 as 8 is to x
6/(2 2/3) = 8/x
6/(8/3) = 8/x
6x = 8 * 8/3
6x = 64/3
x = 32/9
x = 3 5/9
Oil:
6 is to 1/4 as 8 is to x
6/(1/4) = 8/x
6x = 1/4 * 8
6x = 2
x = 2/6
x = 1/3
Answer:
Step-by-step explanation:
a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying. Ex
3
(2)(9)

18
=6
If I have to , I'll include my fractional equation with the arrows. answer is:
x = 6
