Answer:
$65
Step-by-step explanation:
Let
x = original price of the item
Mai buys one item and saves $13,
This means 20% of the original price of the item = $13
20% of x = 13
20/100 * x = 13
0.2 * x = 13
0.2x = 13
Divide both sides by 0.2
x = 13 / 0.2
= 65
x = $65
Therefore, the original price of the item is $65
Answer: x - 5
Step-by-step explanation:
Since, the area of the rectangle =
Length of the rectangle = x+5
Let the width of the rectangle = b
Thus, the area of the rectangle =
⇒
⇒
⇒
Therefore, the expression that shows the width of the rectangle = x-5
Answer:
∠AB=9
Step-by-step explanation:
<em>the pyagrothyes therom= </em><em>+</em><em>=</em>
<em>to find ∠AB we need to find the height of the triangle.</em>
<em>replace the variables:</em>
<em>+</em><em>=</em>
<em>=</em><em>-</em><em>=</em>
<em>simplify:</em>
<em>81-36=</em>
<em>now we solve for ∠AB</em>
<em>replace the variables:</em>
<em>+</em><em>=</em>
<em>simplify:</em>
<em>36+45=</em>
<em>=9</em>
