Answer: y = -90, 90

Step-by-step explanation:

     To solve this, we will isolate the variable.

 Given:

10 = |\frac{y}{9}|

 Absolute value:

10 = \frac{y}{9}     &     -10 = \frac{y}{9}

 Multiply both sides of both equations by 9:

90 = y    &     -90 = y

 Answer:

y = -90, 90

An isosceles triangle has a perimeter (9y-15)cm. what is the length of the remaining equal sides of it's third side is (3y-7) cm
ozzi

The length of each of the equal sides is become x = (3y-4) cm

According to the statement

we have given that the perimeter of the isosceles triangle and length of third side. and we have to find the length of same side of triangle.

So,

An isosceles triangle is a triangle that has two sides of equal length.

Let the equal sides of isosceles triangle be x cm each.

We know that the

Sum of sides of a triangle = perimeter

x+x+(3y-7) = 9y-15

2x = 9y-3y-15+7

After solving the equation it become

2x= 6y-8

x=(6y-8)/2

Now the length of equal sides is x=3y-4

So, The length of each of the equal sides is become x = (3y-4) cm
