Solve the equation 58 - 10x ≤ 20 + 9x
drek231 [11]

Answer:

x≥2

Step-by-step explanation:

First, write out the equation as you have it:

58-10x\leq20+9x

Then, add 10x to both sides:

58-10x+10x\leq20+9x+10x\\58\leq20+19x

Next, subtract 20 from both sides:

58-20\leq20-20+19x\\38\leq19x

Finally, divide both sides by 19:

\frac{38}{19}\leq\frac{19x}{19}\\2\leq x

or

x\geq 2

Therefore: the answer to this inequality/equation is: x≥2

if a dealer buys a car from a manufacturer for $20,480 and sells it for $26,808...what is his markup? rounded to the nearest ten
yulyashka [42]

To find the markup, substract the price at which the car was bought from the price at which the car was sold:

26,808-20,480=6328

To find the markup as a percentage from the original price, set 20,480 to be equal to 100%. If <em>x%</em> represents 6328, then:

\begin{gathered} \frac{x}{6328}=\frac{100}{20,480} \\ \Rightarrow x=\frac{100\times6328}{20,480}=30.898\ldots \end{gathered}

To the nearest tenth, 30.898... = 30.9.

Therefore, the markup is equal to 30.9%.
