Answer:
The on the bottom is right.
Step-by-step explanation:
$2.00 more.
gathered info from question:
Kai paid $45
Cole paid $24
It is $6 for each pack of pens
So I did 24- 6 (pack of pens) = 18 (what he used for calculators) and then did 18/2 because he bought two calculators. He paid 9 dollars for each calculator
Kai bought two packs of pens = 12 dollars. 45-12=33, how much he used for the calculators. He bought three calculators so I did 33/3=11. He used 11 dollars for each calculator.
11-9=2.
Kai paid $2.00 more than Cole.
Please mark be brainliest :)
Rearrange to get x on its own on one side of the equation:
x = 57 - 11
x = 46
(3x−9x)+(12+8)
Answer
−6x+20
Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
