n = 3(k+m)

n = 3k + 3m

3m = -3k + n

Answer:

m = (n/3) - k

Step-by-step explanation:

n = 3(k + m)

n = 3k + 3m

n - 3k = 3m

3m/3 = (n - 3k)/3

m = (n/3) - k

I need help understanding how to solve this please ASAP!!!!
LenaWriter [7]

Answer:

17 cm

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse

8^2 + 15^2 =c^2

64+225 = c^2

289 = c^2

Take the square root of each side

sqrt(289) = sqrt(c^2)

17 = c

Answer:

<em>Both equal sides have a length of 29 cm.</em>

<em>The third inequal side is 9 cm.</em>

Step-by-step explanation:

<u>System of Equations</u>

With the data provided in the problem, we can form a system of two equations with two unknowns.

Let's call x to each equal side of the isosceles triangle and y to the other side. One condition states that each equal side is 2 cm more than three times the other side. It can be written as:

x=3y+2

We also know the perimeter of the triangle is 67 cm. Since we have to equal sides to x:

x+x+y=67

2x+y=67

Let's put together both equations:

x=3y+2

2x+y=67

To solve the system, we can use the x from the first equation and replace it into the second equation:

2(3y+2)+y=67

Operating:

6y+4+y=67

Joining like terms:

7y=67-4=63

Solving for y:

y=63/7=9

The third inequal side is 9 cm. Now find the value of x.

x=3y+2=3(9)+2=27+2=29

Both equal sides have a length of 29 cm.
