Let x represent the first number, then x-7 represents the second number

Assume the numbers are whole numbers (no negative numbers), then the smallest value that x could be is 8. Thus, the first number is 8 and the second number is 1. The LCM is 8.

Let's increase x by one number so that x=9, then the second number is 2. The LCM is 18.

Let's increase x again by one number so x=10, then the second number is 3. The LCM is 30.

You could continue this to discover that the LCM will be x(x-7) between x=8 and x=13.

So what happens at x=14? First digit is 14 and the second digit is 7. The LCM is 14.

This will occur for all x-values that are multiples of 7.

Answer: when x is a multiple of 7, the LCM is x. when x is not a multiple of 7, the LCM is x(x-7).

Lady bird [3.3K]
For this case, we have that the remaining percentage of food belongs to fats.
 We have then that the percentage that belongs to fats is:
 100 - 48 - 13 = 39%
 Then, the amount of kilocalories from fats is:
 (0.39) * (1120) = 436.8
 Answer:
 
the meal has 436.8 kilocalories of fat

A hiker is walking down a mountain. She walked​ 5,978 feet in 17 minutes. In that​ time, she descended​ 1,024 feet from the top
olya-2409 [2.1K]

Answer:

63.5 feet/minute

Step-by-step explanation:

She first descended 1,024 feet in 17 minutes

Then she descended 500 feet in 7 minutes

The total feet descended is 1,024 + 500 = 1,524 feet

The total time to descend is 17 + 7 = 24 minutes

The average rate of change in altitude is  

Altitude descended / time

1,524 feet / 24 minutes

63.5 feet /minute

Cam and Madison were investing money into two different accounts. They both invested $550
Arlecino [84]

Answer:

After 5 years, Cam's account will have $ 616.04 while Madison's account will have $ 638.53.

Step-by-step explanation:

Given that Cam and Madison were investing money into two different accounts, both investing $ 550 each, and Cam invested into an account at an annual interest rate of 2.7% compounded monthly while

Madison invested into an account that had an annual interest rate of 3% compounded quarterly, to determine the balances of both accounts after 5 years, the following calculations must be performed:

Cam

X = 550 (1 + 0.027 / 12) ^ 5x12

X = 550 (1 + 0.027 / 12) ^ 60

X = 616.04

Madison

X = 550 (1 + 0.03 / 3) ^ 5x3

X = 550 (1 + 0.03 / 3) ^ 15

X = 638.53

Thus, after 5 years, Cam's account will have $ 616.04 while Madison's account will have $ 638.53.

How to solve y-b/x=m for y
Slav-nsk [51]
To solve for m we want to get m by itself on one side of the equals sign, with everything else on the other side. First we subtract b from both sides, to get it out of the right side of the equation:
y - b = mx + b - b
y - b = mx
Now we divide both sides by x, to get m completely by itself:
(y-b)/x = (mx)/x
(y-b)/x = m
So m is equal to (y-b)/x.
