The answer is A because 12.5 plus 0.75 is 13.25. Then muiltiply it with g to find total cost.
X intercept: (-4)
y intercept: (8)
Answer:
73.4%
Step-by-step explanation:
The ratio of acid to mixture volume is ...
(0.62·175 +1.00·75)/(175 +75) = 183.5/250 = 0.734 = 73.4%
73.4% of the resulting mixture is acid.
-2(4w-1)=3(4w+2)
-8w+2=12w+6
-20w=4
w=-0.2

This is because 
And 
For this reason, 
Positive indices mean we have to multiply the same number twice or thrice based on the value of the index. On the other hand, negative indices mean we have to divide by the same number twice or thrice based on the value of the index.
