This question states that Lake Lopez began at a depth of 515 inches, then increased by 82 inches, then decreased by 119 inches. To model this, we will use addition for the increase and subtraction for the decrease; this will signify a positive/negative change in the depth. This can be modeled by the expression below:
515 + 82 - 119
597 - 119
478
Therefore, the water depth at the end of the summer was 478 inches.
Hope this helps!
Answer:
When the solution is negative
Step-by-step explanation:
One example, let's say you are buying pens and each pen cost 3 dollars and you cannot spend more than 15 dollars, how many pens can you buy?
The inequality would be 3x < 15, so any negative solution is not reasonable because you cannot buy negative pens. The same goes for most real-world problems dealing with time, money, or distance.
Explanation:
The number of times the 6-sided number cube will be rolled will is
Let the numbers greater than 4 be represented below as
The number of sample space will be
The probability of rolling a number greater than 4 will be calculated below as
Hence,
To calculate the number of times a number greater than 4 will be rolled will be calculated below as
Hence,
The final answer is
He has 30 gallons left
5/8 = 50/80
80-50=30
Depend on the comparison. if u want to see greater or less then use = < > or the difrent subtract . add if finding the total.
