I am not sure but I think this is what it means by.
 You can substitute 4 for an example for x.
 5(4+2)          5(4)+10
 5(6)              20+10
 30                    30

How old would someone be if they were born on the 30th october 1992 ????
alexdok [17]
Today is March, 19th 2016
so from 1992 have been: 2016 - 1992 = 24 years
but the date is from October 30th, so we are not at 24 years just yet, we are at 23 years and the months and days since last 30th October, that is:
November + December + January + February = 4 months
and some days more, 19 days because today is 19th, so the total is:
23 years, 4 months, 19 days

To solve 493x = 3432x 1, write each side of the equation in terms of base.
iVinArrow [24]

The solution of the equation in terms of the base is \rm x = \dfrac{-1}{2939}\\\\.

Given that

Equation; \rm 493x= 3432x+1

We have to find

The solution of the equation in terms of base.

According to the question

To determine the solution of the equation following all the steps given below.

Equation; \rm 493x= 3432x+1

Then,

\rm 493x= 3432x+1\\\\493x-3432x=1\\\\-2939x=1\\\\x = \dfrac{-1}{2939}\\\\

Hence, the solution of the equation in terms of the base is \rm x = \dfrac{-1}{2939}\\\\.

What is the tires weight in pounds?
poizon [28]
Hey!


To solve this problem we must begin by writing out an equation.

Here's the equation I've created.

<em>520 ÷ </em><span><em>453.592 = ?</em>

Now we solve our created equation to get the answer.

<em>520 </em></span><em>÷ 453.592 = 1.1464046985</em>

That could be our final answer but sometimes you might want to round.

<em>So, the tires weight in pounds is</em>  1.1464046985  <em>or</em>  1.15.

Hope this helps!
