Answer:
a3= -343
divade both side by 3 to make a the subject
a3/3= -343/3
a = -114.3
2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)

Given:
pH = 4.2 of tomato
Required:
hydrogen-ion concentration [H+]| for tomato juice
Solution:
The formula for the pH relating hydrogen ion concentration is pH =
-log[H+] where H+ is the hydrogen ion concentration. so, substitute the value
of pH
pH = -log[H+]
4 = - log[H+]
-4 = log[H+]
10^-4 = [H+]
[H+] = 1x10^-4M
EXPLANATION
Let's consider the facts:
a. Traveled = 16 feet
|-16| = 16
The porpoise is 16 feet from the surface of the water.
b. Withdrawal = -$250
|-250| = 250
Chelsea paid the electric company $250 dollars
c. Temperature = -54
|-54| = 54
The temperature is 54 degrees below zero.
d. Distance= 34 miles east
|34| = 34
The distance between Adelphi and Sterling is 34 miles.
