Answer: 20 hours

Step-by-step explanation:

Equation: 15x = 300

Isolate the variable.

Divide both sides by 15:   ¹⁵ˣ⁄₁₅ = ³⁰⁰⁄₁₅

x = 20

Ivan needs to work 20 hours in order to afford the bicycle.

\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}
\qquad csc(\theta)=\cfrac{1}{sin(\theta)}
\\\\\\
sin^2(\theta)+cos^2(\theta)=1\\\\
-------------------------------\\\\

\bf \cfrac{cos(\theta )cot(\theta )}{1-sin(\theta )}-1=csc(\theta )\\\\
-------------------------------\\\\
\cfrac{cos(\theta )\cdot \frac{cos(\theta )}{sin(\theta )}}{1-sin(\theta )}-1\implies \cfrac{\frac{cos^2(\theta )}{sin(\theta )}}{\frac{1-sin(\theta )}{1}}-1\implies 
\cfrac{cos^2(\theta )}{sin(\theta )}\cdot \cfrac{1}{1-sin(\theta )}-1
\\\\\\
\cfrac{cos^2(\theta )}{sin(\theta )[1-sin(\theta )]}-1\implies 
\cfrac{cos^2(\theta )-1[sin(\theta )[1-sin(\theta )]]}{sin(\theta )[1-sin(\theta )]}

\bf \cfrac{cos^2(\theta )-1[sin(\theta )-sin^2(\theta )]}{sin(\theta )[1-sin(\theta )]}\implies \cfrac{cos^2(\theta )-sin(\theta )+sin^2(\theta )}{sin(\theta )[1-sin(\theta )]}
\\\\\\
\cfrac{cos^2(\theta )+sin^2(\theta )-sin(\theta )}{sin(\theta )[1-sin(\theta )]}\implies \cfrac{\underline{1-sin(\theta )}}{sin(\theta )\underline{[1-sin(\theta )]}}
\\\\\\
\cfrac{1}{sin(\theta )}\implies csc(\theta )

I need this answer plzzz!!
Dmitriy789 [7]

Answer: True, False, False, False, False

<u>Step-by-step explanation:</u>

a) 5x - 7(x - 1)

   5x - 7x + 7

         -2x + 7   ⇒  a = -2, b = 7   <em>One Solution</em>

b) 3(x - 5) - 7

   3x - 15 - 7

       3x - 22   ⇒  a = 3, b = -22   <em>One Solution</em>

c) 2 - 7x + 3 + 4x

  4x - 7x + 3 + 2  

              -3x + 5  ⇒   a = -3, b = 5   <em>One Solution</em>    

d) -3(x - 3) - 1

   -3x + 9 - 1

       -3x + 8   ⇒   a = -3, b = 8   <em>One Solution</em>

e) -5x + 2 + 2x + 4

   -5x + 2x + 2 + 4

                  -3x + 6  ⇒   a = -3, b = 6   <em>One Solution</em>
