Answer:
x²+5x-10=0
x²+(2-7)x-10=0
x²+2x-7x-10=0
x(x+2)-7(x+2)=0
=x+2=0
=x=-2
=x-7=0
=x=7
hope may be right.....
Step-by-step explanation:
Let
be the most the manager can pay the suppliers.
Then, we know from the information given in the question that the manager needs a 30% markup based on cost.
Therefore, the guiding equation will be:

because $10 is the most people will pay for a neck warmer.
Thus, the above equation will become:




Thus, the most a manager can pay the suppliers for neck warmers and still keep the selling price at $10 is $7.69
To figure out your question, just divide 999,999 by 9.
999,999/9 = 111,111
Hi there!
6/7 itself is already simplified in it's smallest form.
6/7 = 6/7.
In a decimal form this is 0.857143.
Hope this helps!
No, you would only need to multiply 16 by 5 once
