What is the sum of 3 consecutive integers of 87
Leviafan [203]
Hey there! Hello!

So, to set this problem up, all you need to do is imagine that the smallest number of these consecutive integers is x. The next two numbers will be x+1, then x+2, and that, altogether, will equal 87. In a problem, this will look like this:

x+x+1+x+2=87

All we need to do is solve for x! We can simplify the problem by combining like terms:

x+x+x+1+2=3x+3=87
3x+3-3=87-3
3x/3=84/3
x=28

Now that we know what x is, we can plug it into our original problem:

x+x+1+x+2 = 28+29+30=87

Hope this helped you out! Feel free to ask me any additional questions if you need further clarification. :-)

At a swimming pool there are 2 managers 8 lifeguards 3 concession stand clerks and 2 maintenance people. If a person is selected
SashulF [63]

Step-by-step explanation:

The total number of people mentioned in this problem is 15. 15 will be the denominator for the probability in fraction form. The sum of the # of people that include lifeguards and managers will be the numerator.

Therefore, the probability that the person picked is either a manager or a lifeguard is 10/15 [because there are 2 managers and 8 lifeguards; 2 + 8 =10].

<u>Fraction form of probability: 10/15</u>

<u>Decimal form: 0.6 repeated</u>

<u>Percent form: about 66.67%</u>
