The answer should be 24, because you can mark out 5,and 10 cuz it doesn’t make since
-2x^2 + 5x -3 =0
Find the discriminate:
In the given formula a = -2, b = 5 and c = -3
The discriminate is found using the formula b^2 - 4(ac)
Replace the letters with their values:
5^2 - 4(-2*-3)
25 - 4*6
25-24 = 1
When the discriminate is greater than or equal to 0, there are two real solutions.
The answer is c) 2
Answer:
B grade

Hello,
You have 7 balloons and in total, they cost 9.1. dollars. To find the unit price per balloon simply divide 9.1. by 7.
You'll get 1.3, OR 1.30.
To check your answer simply use inverse operations. Multiply 7 by 1.3 or 1.30 (it doesn't matter); you'll end up with the starting value 9.1.
Thus, the unit price per balloon is $1.30.
