Answer:
Step-by-step explanation:
x= cost per gallon
10x=23
x=2.3
2.3*15= 34.5
Change it into the form
ax^2 + bx + c = 0
x^2 + 13x + 0 = 0
This equation has a common factor, x. Factorise it out.
<h2>x (x + 13) = 0</h2>
Answer:
$6000
Step-by-step explanation:
so basically, 25% of the 100% value is gone, right? which means that 75% of the value would remain. After that, all is easy. 8000*0.75, since 75% is 0.75, and the answer of that is 6000, so the current value is 6000 dollars.
Answer:

Step-by-step explanation:
y = 40t
t = tutoring hours for ONE unique student...
