One leg of a triangle is 7 inches. another leg measures 5 inches. if the perimeter of the triangle is 19 inches, find the length
Setler79 [48]

SOLUTION

A triangle has three sides. The sides of this triangle are 7 inches, 5inches and the unknown side.

Let the unknown side be x inches.

Perimeter is distance around a plane shape.

The perimeter of this triangle is 19,

\begin{gathered} \text{  That is the perimeter  1}9=7+5+x \\ 19\text{ = 12 }+x \\ x\text{ = 19 - 12 } \\ x\text{ = 7 inches } \end{gathered}

Therefore, the other side is 7 inches

PLEASE HELP!! this is due really soon
GuDViN [60]

Answer:  There are 467 students at Holmes Junior High.

              There are 342 students at Harper Junior High.

_________________________________________________

Step-by-step explanation:

_________________________________________________

Let " x" represent the number of students at Harper Jr. High.

Holmes Junior has:  " (x + 125) "  students .

Harper Junior High has:  " x"  students:

_________________________________________________

Together, the total number of students equal:  " 809 " students.

so:  " x + (x + 125) = 809 " .

We want to solve for "x" and " (x + 125)" .

We want to solve for "x" ;  

then we can solve for " (x + 125) "  by adding "125" ;

                                                      to our "solved value for "x" ;

____________________________________________

  x + (x + 125)  = 809 .

 →  1x + 1x + 125 = 809 ;

 →   2x + 125 = 809  ;

Now, subtract "125" from each side of the equation:

 →   2x + 125 - 125 = 809 - 125 ;

 →   2x  =  684 ;

Now, divide each side of the equation by "2" ;

    to isolate:  "x" on one side of the equation; & to solve for "x" ;

 →   2x/ 2 =  684 / 2  ;

to get:

 →    x = 342 ;  which is the total number of students at Harper Jr. High.

Now,  to solve for:  " (x + 125)" ;

Plug in:  "342" for "x" ;

→  " (342 + 125) " = " 467 " '

→  which is the total number of students at Holmes Jr. High.

_________________________________________________

Do our answers make sense:

Does:  " 342 + 467 =?  809 ?? " ;

         →  Yes!

_________________________________________________

Answer:  There are 467 students at Holmes Junior High.

               There are 342 students at Harper Junior High.
