Answer:

First Place wins in 15 events

Second Place wins in 12 events

Step-by-step explanation:

Let

the number of events winning first place be "f"

the number of events winning second place be "s"

Total 27 swimming events, we can write:

f+s=27

First place wins is THREE MORE than 2nd place wins, so we can write:

f=s+3

Replacing 2nd equation in 1st equation, we can solve for "s":

f+s=27\\(s+3)+s=27\\2s+3=27\\2s=24\\s=12

We know

f = s + 3

so,

f = 12 + 3

f = 15

Thus,

<u>First Place wins in 15 events</u>

<u>Second Place wins in 12 events</u>

Jerry multiplied 3.04 x 7.091 and got the product 2.155664. Is his answer reasonable? Why or why not?
Readme [11.4K]

First we multiply the numbers ignoring the decimal and then place the decimal in the position

3.04 *7.091 = 2155664

Now the first number has two digits after the decimal and the second number has three digits after the decimal.

Therefore in the final result we have to move the decimal (2+3) =5 place from the left,

So the answer would be 21.55664

So, the correct answer is 21.55664

Jerry calculated the answer correctly , but made an error in the placement of the decimal point.  The answer is not reasonable because 2.155664 and 21.55664 mean two completely different answer far apart from each other

Can you add and subtract integers and surds together?
Ne4ueva [31]

Answer:

Both of these examples are wrong. You cannot add/subtract integers and square roots together, however, you could add square roots together if they have the same number under the square root. For example, 2 - 2√6 will stay as 2 - 2√6 because they aren't like terms. 25 + 5√5 + 5√5 + 5 = 30 + 10√5 because 25 + 5 = 30 and 5√5 + 5√5 = 10√5. We can add 5√5 and 5√5 together because they have the same number under the square root. If we were to compute √2 + √3, we would just leave it as is because they don't have the same number under the square root.

Solve by factoring<br> x^2-10=9x
BabaBlast [244]

Answer:

x=10

Step-by-step explanation:

x^2 - 10 - (9x) = 0

x^2 - 9x - 10 = 0

(x - 10) + (x + 1) = 0

x= 10

x = -1
