Answer:
Let v = ml of 100% vinegar
Then 150-v = ml of dressing
v + .05(150-v) = .24(150)
v + 7.5 - .05v = 36
.95v = 28.5
v = 28.5/.95
v = 30 ml of vinegar
dressing = 150-30 = 120 ml

Step-by-step explanation:
➨ We can also solve by completing both squares, however. Since we can pull out the square root.
➩ Define of Absolute Value/Square Root
➩
Thus, our new equation is ➩
To solve an absolute-value equation, let there be two conditions.
➨ Where x ≥ 0
Move x to another side
➨ Where x < 0
Answer: 180 miles x 3 hours = 540
540/2 = 270
270 is the average speed
Step-by-step explanation:
1 (B), because 3+-2=1, and 5+-4=1, which amounts to 1/1, or whole number 1.
