Answer:

n = 12.3

Step-by-step explanation:

I'm assuming we're looking for n, to find it, we need to isolate it.

Our equation will be solved through PEMDAS :

Parenthesis

Exponent

Multiply/Divide

Add/Subtract

n / 10^2 = 0.123

Get rid of the exponent by applying it to 10,

10^2 = 100

n/100 = 0.123

Now to get rid of the division, multiply the denominator (100) to both sides.

n/100 * 100 = 0.123 * 100

n = 12.3

  • HJ = 23.5 in

\textsf{  \underline{\underline{Steps to solve the problem} }:}

Take HJ = a, GH = b and GJ = c

  • a = b + 2

  • c = a + b - 17

  • a + b + c = 73

put the value of a from equation 1 in equation 2

  • c = (b + 2) + b − 17

  • c = 2b − 15

now, put the value of a and c in equation 3

  • b + 2 + b + 2b − 15 = 73

  • 4b − 13 = 73

  • 4b = 86

  • b = 21.5 in

Now, we need to find HJ (a)

  • a = b + 2

  • a = 21.5 + 2

  • a = 23.5 in

{ \qquad \large \sf {Conclusion} :}

  • HJ = 23.5 in
