How old am i if 500 reduced by 4 times my age is 184

Mathematics
1 answer:
Lunna [17]2 years ago
8 0

Answer:

79 years old

Step-by-step explanation:

Let's say your age is x.

The problem says "500 reduced by 4 times my age is 184", so we convert this to math:

- "4 times my age" ⇒ 4 * x = 4x

- "500 reduced by" ⇒ 500 - (something)

- "500 reduced by 4 times my age" ⇒ 500 - 4x

- "is 184" ⇒ = 184

- "500 reduced by 4 times my age is 184" ⇒ 500 - 4x = 184

Now, we simply solve for x:

500 - 4x = 184

4x = 500 - 184 = 316

x = 79

Thus, you are 79 years old.

Hope this helps!

The cost of Spectrum Internet is $60 per month plus a one time $35 installation fee. How much would it cost to have internet for
Murljashka [212]

Answer:

$755

Step-by-step explanation:

You can use the formula c = 60m + 35 for this. c is the cost and m is the number of months. Since a year is 12 months, 60m = 60*12 = 720. Then add the one time fee of $35. 720 + 35 = 755.

Add or Subtract to Simplify:<br> (x5 + x3) - (6x - x3 + 6x5)
ziro4ka [17]

Answer:

\boxed{ \bold{   \boxed{ \sf{ - 5 {x}^{5}  + 2 {x}^{3}  - 6x}}}}

Step-by-step explanation:

\sf{( {x}^{5}  +  {x}^{3} ) - (6x -  {x}^{3}  + 6 {x}^{5}) }

When there is a ( - ) in front of an expression in parentheses , change the sign of each term.

Also, remove the parentheses

⇒\sf{ {x}^{5}  +  {x}^{3}  - 6x +  {x}^{3}  - 6 {x}^{5} }

Collect like terms

⇒\sf{ {x}^{5}  - 6 {x}^{5}  +  {x}^{3}  +  {x}^{3}  - 6x}

⇒\sf{ - 5 {x}^{5}  + 2 {x}^{3}  - 6x}

Hope I helped!

Best regards!!

Write the slope-intercept form of the equation of the line that is perpendicular to and passes through Point X. Show all work fo
Semmy [17]

Answer:

y =\dfrac{12}{5}x + 22

Step-by-step explanation:

Slope-intercept form of line:

First find the slope of the line AB. ie, m

Slope of the perpendicular line = -1/m

(2 , 3)  ⇒ x₁ = 2 & y₁ = 3  

(-10, 8)  ⇒ x₂ = -10 & y₂ = 8

\boxed{Slope=\dfrac{y_2-y_1}{x_2-x_1}}

          = \dfrac{8-3}{-10-2}\\\\=\dfrac{5}{-12}\\\\=\dfrac{-5}{12}

\sf slope \ of \ the \ perpendicular \ line \ m_1 = \dfrac{-1}{m}= -1 \ \div \dfrac{-5}{12}

                                                   \sf = -1 * \dfrac{12}{-5}=\dfrac{12}{5}

Equation of the required line: y = mx + b

       y =\dfrac{12}{5}x+b

The line passes through (-5 , 10). Substitute in the above equaiton,

         10 =\dfrac{12}{5}*(-5) + b\\\\ 10 = (-12) + b\\\\

 10 + 12 = b

        b   = 22

Equation of the line:

  y =\dfrac{12}{5}x + 22

Please help!! I dont get it
Mazyrski [523]
This is pretty simple once you think about it, you are probably just making it harder than it needs to be :) So, all you really have to do is plug in the numbers and see which statement is true. So, for the first one, you should work it out with me in the comments. Sorry lol I don't really like giving straight answers. lol
