Answer:
(15*x)+((25)(x-2))=230 THE ANSWER D. X=7
I GOT IT CORRECT
Step-by-step explanation:
Dolls : teddy bears
6 : 7
if 120 dolls are equal to 6 portions,
7 portions,
(120/6) * 7
140 teddy bears
Five squared with the little two and 2 because 5 Times 10 is 50 and five is prime so then from 10 and you get five and two and both five and two are prime
The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.
The answer is it was truly a jam
