X^2-6x=13
(x-3)^2-9=13
(x-3)^2=22
(x-3)= +-sqrt22
x = sqrt22+3 or x = -sqrt22+3
Answer:
B and C
Step-by-step explanation:
I hope this helps :)
Answer:
x=-9
Step-by-step explanation:
13-5x=4-6x
-5x+6x=4-13
x=4-13
x=-9
The answer might be 1/30 ( one over 30)
Using a system of equations, it is found that the manager ordered 261 licorice packages.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The variables for this problem are given by:
- Variable x: number of taffy packages.
- Variable y: number of gumdrop packages.
- Variable z: number of licorice packages.
He ordered a total of 609 packages of candy, hence:
x + y + z = 609.
He ordered 3 times as many taffy packages as gumdrop packages. He ordered the same number of licorice packages as taffy packages, hence:
- x = z = 3y -> y = 0.3333z.
We have to solve the system for z, hence, replacing the data above in the first equation:
z + 0.3333z + z = 609.
2.3333z = 609.
z = 609/2.3333
z = 261.
The manager ordered 261 licorice packages.
