Answer:
3
Explanation:
The smallest whole number that 4 and 6 share when multiplied is 12
Hello.
First, let the number be r.
5 times r is written like this:
Now, add 45:
Now, the sum of 5r+45 is equal to the sum of 85 and 140:
In order to solve this equation, we need to add 85 and 140:
Now, subtract 45 from both sides:
The last step is to divide both sides by 5:
Therefore, the answer is
I hope it helps.
Have a nice day.
1: Bettina's 60, and Melvina's 20.

You need to use a system of equations with 2 variables
where x= # of paintbrushes bought
and y= # of paint units bought
the first equation would be
.95x+.99y=4.87
Usually there is more information given in these problems so that you can make the second equation. Did the problem say how many total items were bought or anything else because given this information you cannot make a second equation and therefore cannot solve for both variables. Also, the wording is unclear, did she spend 4.87 on just paintbrushes or both brushes and paint.
Answer:
The answer to the equation is W=1.8
