1 answer:
Answer: the smaller number is 8. The larger number is 38
Step-by-step explanation:
Let x represent the smaller number.
The The larger of the two numbers is eight more than three times the smaller number. It means that the larger number is 3x + 8
The sum of the two numbers is 48. It means that
x + 3x + 8 = 48
4x + 8 = 48
4x = 48 - 8 = 40
x = 40/4 = 10
Substituting x = 10 into 3x + 8, it becomes
3 × 10 + 8 = 38

So if $42 was 70% of the original price that means you saved 30% so work out 30% of $42 then add it to the $42 = $12.60 + $42
Explanation:
Formula to calculate pH of a chemical or solution is as follows.
pH = ![-log [H^{+}]](https://tex.z-dn.net/?f=-log%20%5BH%5E%7B%2B%7D%5D)
Therefore, calculate the pH of given chemicals as follows.
1). Oven cleaner
pH =
= ![-log [10^{-13}]](https://tex.z-dn.net/?f=-log%20%5B10%5E%7B-13%7D%5D)
= 13
2). Water
pH =
= ![-log [7 \times 10^{-7}]](https://tex.z-dn.net/?f=-log%20%5B7%20%5Ctimes%2010%5E%7B-7%7D%5D)
= 6.15
3). Blood
pH =
= ![-log [4 \times 10^{-8}]](https://tex.z-dn.net/?f=-log%20%5B4%20%5Ctimes%2010%5E%7B-8%7D%5D)
= 7.40
4). Vinegar
pH =
= ![-log [63 \times 10^{-4}]](https://tex.z-dn.net/?f=-log%20%5B63%20%5Ctimes%2010%5E%7B-4%7D%5D)
= 2.20
