Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86

Answer:
The equation for the problem is:
The amount of bracelets you should sell is the price of the soccer cleats divided by 0.75
Step-by-step explanation:
Let's call <em>b</em> the amount of bracelets and <em>s</em> the price of the soccer cleats.
If you make a profit of $0.75 for every bracelet you sell, then 0.75 times the amount of bracelets sold should be equal to the price of the soccer cleats.
This can be written like this:
<em>(this is the equation)</em>
As b (amount of bracelets) is our unknown variable, then that's the term we should isolate. To do so we divide each side of the equation by 0.75
<em>(this is the amount of bracelets you should sell)</em>
Then, the equation for the problem is:
and the amount of bracelets you should sell is the price of the soccer cleats divided by 0.75
