Answer:
$55
Step-by-step explanation:
<u><em>Given:</em></u>
<em>A pair of shoes is $50, plus 10% tax. </em>
<u><em>To Find:</em></u>
<em>What is the total amount you will pay?</em>
<u><em>Solve:</em></u>
<em>Tax = Increase - Add on</em>
<em>Thus,</em>
<em>$50 × 10% = 5</em>
<em>$50 + 5 = $55</em>
<em>Hence, the total amount you will pay is $55.</em>

Is the question mark in the actual expression?
1) Draw a right triangle with these measures:
angle with the horizontal: 6 degress
horizontal segment: 5
height: x
2) Definition of tangent : tan(6°) = opposite leg / adjacent leg = x / 5 =>
3) Solve for
x = 5tan(6°) = 0.53 miles
Answer: 0.53 miles
2.14x - 12.18 = -5.76
Isolate the x, do the opposite of PEMDAS (Parenthesis, Exponents (and roots), Multiplication, Division, Addition, Subtraction).
2.14x - 12.18 = - 5.76
First add 12.18 to both sides to isolate the x
2.14x - 12.18 (+12.18) = - 5.76 (+12.18)
2.14x = - 5.76 + 12.18
2.14x = 6.42
Next, isolate the x by dividing 2.14 from both sides
2.14x/2.14 = 6.42/2.14
x = 6.42/2.14
x = 3
3 is your solution to the equation
hope this helps
