An isosceles triangle has two sides of equal length. The third side is five less than twice the length of one of the other sides

4vir4ik [10]

Answer:

9

Step-by-step explanation:

We can set up a systems of equations to find the value of the third side.

Let's assume that $x$ is the length of both sides 1 and 2. Let's also assume that $y$ is the length of the third side.

We know that $x + x + y = 23$ , and looking at the first clue we can make the equation $y = 2x-5$ .

We can substitute y into the equation $x + x + y = 23$ .

$x + x + (2x-5) = 23\\\\2x + 2x-5 = 23\\4x-5 = 23\\4x = 28\\x = 7$

So the length of the side that is the same as the second is 7.

Now we can plug this into the equation $y = 2x-5$ to find $y$ .

$y = 2(7) - 5\\\\y = 14-5\\\\y = 9$

Hope this helped!

Last year 762 students voted in the student council election at San Bruno Middle School this year 721 students voted to the near

Soloha48 [4]

Answer:

Percent change = 5.4%

Step-by-step explanation:

Given:

Number of students voted last year = 762

Number of students voted this year = 721

Change in the number of students who voted from last year to this year is given by the difference of their number. This gives,

Change in the number of students that voted = 762 - 721 = 41

Now, percentage change in the number of students that voted is given as:

$\textrm{Pecent change}=\frac{\textrm{Change in number}}{\textrm{Number last year}}\times 100\\\\\textrm{Pecent change}=\frac{41}{762}\times 100\\\\\textrm{Pecent change}=\frac{4100}{762}=5.38\%\approx 5.4\%$

Therefore, the percent change in the number of students that voted is 5.4%.
