Answer:

Answers of given questions are written below :

  • 1) x = 7.52
  • 2) x = 11
  • 3) x = 2.5

Step-by-step explanation:

\large{\tt{\underline{\underline{\purple{SOLUTION : - }}}}}

5.37 + x = 12.89

\implies{\tt{5.37 + x = 12.89}}

\implies{\tt{ x = 12.89 - 5.37}}

\implies{\tt{ x = 7.52}}

\star{\underline{\boxed{\sf{\red{ x = 7.52}}}}}

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>7.52</u>

\begin{gathered}\end{gathered}

42 = 6x - 24

\longmapsto{\sf{42 = 6x - 24}}

\longmapsto{\sf{ 6x = 42  +  24}}

\longmapsto{\sf{ 6x = 66}}

\longmapsto{\sf{x = \dfrac{66}{3}}}

\longmapsto{\sf{x = 11}}

\star{\underline{\boxed{\sf{\red{ x = 11}}}}}

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>11</u><u>.</u>

\begin{gathered}\end{gathered}

10x + 25 = 50

{\longrightarrow{\rm{10x + 25 = 50}}}

{\longrightarrow{\rm{10x= 50 - 25}}}

{\longrightarrow{\rm{10x= 25}}}

{\longrightarrow{\rm{x= \dfrac{25}{10}}}}

{\longrightarrow{\rm{x=2.5}}}

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>2</u><u>.</u><u>5</u><u>.</u>

\rule{300}{2.5}

Answer:

7.52

Step-by-step explanation:

5.37 + x = 12.89

In order to solve this equation, we must isolate the variable, x.

1.) To do this, subtract 5.37 on both sides of the equation.

5.37 + x = 12.89

-5.37         -5.37

x = 7.52

Therefore, x = 7.52

Jon bought a printer for $189 and a set of printer cartridges for $192. Sales tax on these items was 6.5%. What is Jon's total b
julia-pushkina [17]
So first we need to find the total before tax. Let's add up the two prices:

189+192=381

So we know that the total before tax is $381. Now we are told that the sales tax on these items is 6.5%. It would be easier for us to convert 6.5% to a decimal in order to multiply. Let's convert 6.5% to a decimal by dividing by 100:

\frac{6.5}{100}=0.065

Now that we have the sales tax in decimal form, let's multiply this sales tax by the total amount of the items before tax ($381):

381*0.065=24.77

This means that $24.77 is the tax for this purchase. To find the total amount that Jon paid for these items after tax, you must add the tax to the total amount before tax to give you:

381+24.77=405.77

So now we know that Jon's total bill for these items is $405.77.

Montano1993 [528]

Answer:

10 feet

Step-by-step explanation:

Use the volume formula, V = lwh, to solve for w

Plug in the values we know:

V = lwh

250 = (5)(w)(5)

250 = 25w

10 = w

So, the width is 10 feet
