The depth of two lakes is measured at multiple spots. For the first lake, the mean depth is about 45 feet with a standard deviation of 8 feet.
For the second lake, the mean depth is about 60 feet with a standard deviation of 27 feet.
Noah says the second lake is generally deeper than the first lake.
Do you agree with Noah? Explain why or why not.

Okay so n is going to represent our first number. since the second number of five times greater than n, the second number will be represented as 5n. for us to figure out the two  numbers we need to have  the value of n first. this is going to be done by adding the two numbers together, n and 5n. it can be simplified as 6n, which the problem states is equal to 72. divide 72 by 6n and you can solve for n.  n+5n=726n=72n=(72/6)n=12  now that we know the value of n, we have to multiply 5 times 12 which equals 60. so our two numbers/integers are 12 and 60

85=x+42x represents how much she needs to save and if x plus forty two equals eighty five x equals forty three
