Answer:

Equation: 30=2(x-2)+2(2x+3)

x:\frac{14}{3}

Step-by-step explanation:

By definition, the perimeter of a figure can be calculated by adding the lenghts of its sides.

Knowing this, you can write the following equation:

P=2(x-2)+2(2x+3) <em> [Equation 1]</em>

According to the data given in the exercise, the perimeter in feet of the fighter is:

P=30

Therefore, you can substitute this values into<em> [Equation 1]:</em>

30=2(x-2)+2(2x+3)

Finally, you must solve for "x" in order to find its value. This is:

30=6x+2\\\\30-2=6x\\\\\frac{28}{6}=x\\\\x=\frac{14}{3}

Seven subtracted from the quotient of a number and 2 is -6
Pachacha [2.7K]
N/2 -7 = -6

add 7 to both sides;
n/2 -7+7 = -6+7

n/2 = 1
multiply both sides by 2 (  or divide by 1/2 ) in order to get n by itself.

n/2 * 2/1 = 1 * 2/1

n = 2
