Answer:
A. $605.32
Step-by-step explanation:
The state tax, city tax, and retirement fund add to 6% of Vaughn's wages, or ...
... $785 · 6% = $47.10
Then after subtracting all the deductions, Vaughn's take-home pay is ...
... $785 -42.25 -90.33 -47.10 = $605.32 . . . . matches A
If 81km = 9L, then 9km = 1L.
So ?km = 22L.
With 22L, Amanda can drive 198km.
Answer:
y = 15x
Step-by-step explanation:
For every hour that has gone by, Marco biked 15 miles, therefore, the equation of the line that shows the relationship between the time, x, and the distance, y, is <em>y = 15x</em>.
Hi there!
To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.
Since
x - 4y = 5,
x = 5 + 4y
3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1
Now that we know y is -1, we can substitute it back into the equation to find x:
y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1
So, your answers are x = 1 and y = -1.
Hope this helps!
