When 5 times a number is added to 45 the answer is the sm of 85 and 140 what is the number

zimovet [89]

Hello.

First, let the number be r.

5 times r is written like this:

$\rm{5r}$

Now, add 45:

$\mathrm{5r+45}$

Now, the sum of 5r+45 is equal to the sum of 85 and 140:

$\mathrm{5r+45=85+140}$

In order to solve this equation, we need to add 85 and 140:

$\mathrm{5r+45=225}$

Now, subtract 45 from both sides:

$\mathrm{5r+45-45=225-45}$

$\mathrm{5r=225-45}$

$\mathrm{5r=180}$

The last step is to divide both sides by 5:

$\mathrm{r=36}$

Therefore, the answer is

$\rm{r=36}$

I hope it helps.

Have a nice day.
