Answer:
Fred has saved $115 while Wilma had saved $230
Step-by-step explanation:
Let the amount saved by Fred be F while the amount saved by Wilma be W
Together, they have saved $345
Mathematically;
F + W = 345 •••••••(i)
We are also told that Wilma has have twice as much money as Fred;
Hence; W = 2F ••••••••(ii)
To get the amount of money they both have, we need to solve the equations simultaneously
Substitute ii into i
F + 2F = 345
3F = 345
F = 345/3
F = 115
But W = 2F
W = 2 * 115
W = 230
Answer:
f(x) = x² - 9x + 18
General Formulas and Concepts:
<u>Algebra I</u>
- Standard Form: ax² + bx + c = 0
- Binomial Roots: (x + a)(x + b)(x + c)(x + ...)
- Expanding by FOIL-ing (First, Outside, Inside, Last)
Step-by-step explanation:
<u>Step 1: Define</u>
Zeros/Roots x = 3, 6
<u>Step 2: Find Function</u>
- Rewrite Binomial Roots: f(x) = (x - 3)(x - 6)
- Expand by FOIL-ing: f(x) = x² - 6x - 3x + 18
- Combine like terms (x): f(x) = x² - 9x + 18
If you're trying to solve for y
-2y = 8
Divide -2 to both sides
Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4
Recall that the median of a set of numbers is the number in the middle of the set, after the numbers have been rearranged from lowest to highest.
From the plot, we get that the number, arranged from lowest to highest are:
The number in the middle of the above set is:
Therefore the median of the given numbers is:
Answer: 42.
