Step-by-step explanation:

<em>it's </em><em>an </em><em>isosceles</em><em> triangle</em><em>,</em>

<em>as </em><em>an </em><em>Isosceles</em><em> triangle</em><em> </em><em>have </em><em>two </em><em>equal</em><em> </em><em>sides </em><em>so</em>

<em>→</em><em> </em><em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>9</em><em> </em><em>=</em><em> </em><em>x </em><em>+</em><em> </em><em>5</em>

<em>→</em><em> </em><em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>5</em><em> </em><em>+</em><em> </em><em>9</em>

<em>→</em><em> </em><em> </em><em>x </em><em>=</em><em> </em><em>1</em><em>4</em>

<em>therefore</em><em>,</em><em> </em><em>value</em><em> </em><em>of </em><em>x </em><em>is </em><em>1</em><em>4</em><em>.</em>

<em>2</em><em>(</em><em>1</em><em>4</em><em>)</em><em> </em><em>-</em><em> </em><em>9</em><em> </em><em>=</em><em> </em><em>2</em><em>8</em><em> </em><em>-</em><em> </em><em>9</em><em> </em><em>=</em><em> </em><em>1</em><em>9</em>

<em>1</em><em>4</em><em> </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>1</em><em>9</em>

<em>hope </em><em>this</em><em> answer</em><em> helps</em><em> you</em><em> dear</em><em> take</em><em> care</em><em>!</em>

A family paid $26.400 as a down payment for a home. If this represents 16% of the price of the home, find the price of the home.
Vlada [557]
The correct answer is:

How to find X if P percent of it is Y. Use the percentage formula Y/P% = X

Convert the problem to an equation using the percentage formula: Y/P% = X
Y is 26,400, P% is 16%, so the equation is 26,400/16% = X
Convert the percentage to a decimal by dividing by 100.
Converting 16% to a decimal: 16/100 = 0.16
Substitute 0.16 for 16% in the equation: 26,400/0.16 = X
Do the math: 26,400/0.16 = X
X = 165,000
So $ 165,000 is the price of the home.

I hope this helps you!!
