Answer:
Natalie saved 16%
Step-by-step explanation:
Natalie saved 16% because 20 divided by 125 is 0.16
When we find percentages our goal is to get something like 0.24 which would mean 24% or 0.14 or 14% in this case it is perfect because we immediately see 0.16 or 16% leaving us with our answer, Natalie got 16% off her new phone.
Answer: 800
Step-by-step explanation:
A distinct real solution is a solution to an equation that occurs once, and differs in value from other solutions. For example, in the equation above there are two distinct real solutions: x = − 13 2 and x = 13 2 . Since they are different, real numbers, the equation has two distinct real solutions.
The value of the discriminant determines how many solutions the quadratic will have. Equation 1: the discriminant was zero, there was only 1 solution. Equation 2: the discriminant was a negative number, there was no solution. Equation 3: the discriminant was a positive number, there were two solutions.
Answer:
x=59/6
Step-by-step explanation:
Let's just say x+y+z=74
x=y-3
z=4y
So if we wanna convert everything into one variable, we get (y-3)+y+4y=74
Simplify and you get 6y=77
Now solve for y, and - 3 to get x
