Answer: 15
Step-by-step explanation:
100-10=90
90/6=15
To solve the problem you must apply the proccedure shown below:
1. You have the following quadratic equation given in the problem:
<span>9x^2+2x-7=0
</span>
2. When you factor it, you obtain:
(9x-7)(x+1)=0
3. Then, you have that the roots of the quadratic equation are:
(9x-7)(x+1)=0
x1=7/9
x2=-1
I believe the value is negative 4. If not, well, try any negative below that, such as -5,6,7,8, etc.

275g is what percent of 2.5 kg?
First, convert "275 g" into "kg".
Note the exact conversion: 1000 g = 1 kg .
So 275 g = (275/1000) kg = 0.275 kg .
0.275 kg = (n/100) * 2.5 kg ;
→ (n/100) * 2.5 = 0.275 ;
____________________________
Divide each side by "(2.5)"
______________________
→ (n/100) = (0.275) / (2.5) ;
→ (n/100) = 0.11 ;
Multiply each side by "100" ;
n = 11 .

The answer is: 11 % .
