72.55 a week is paid in tax
if you divide 290.20 by 4 then you would get a fourth of the amount she makes which is the tax amount.
hope this helps! enjoy!
Answer: x=114
Step-by-step explanation:
To solve for x, we want to isolate x.
[multiply both sides by 5]
[add both sides by 1.8]
[divide both sides by 0.2]
Now, we know that x=114.
Answer:
D.4
Step-by-step explanation:
First, find the slope of the line given. To do so, plot two points that are located on the line, and use the slope equation to solve for the slope.
Let the two points be:
(x₁ , y₁) = (4 , 1)
(x₂ , y₂) = (0, 2)
The slope formula is: <em>m </em> = (y₂ - y₁)/(x₂ - x₁)
Plug in the corresponding number to the corresponding variables.
<em>m</em> = (2 - 1)/(0 - 4)
<em>m</em> = 1/-4
<em>m</em> = -(1/4)
The slope of the line given is - 1/4. To find the line perpendicular to it, flip the fraction and the sign.
A line with the slope of (-1/4)'s perpendicular line would be (4).
D. 4 is your answer.

Part A: The y-intercept is 5. If you look to the data, when x=0, y=5. This means that the turtle started off 5 miles away from its nest. (at 0 hours, the distance away from his nest was 5 miles)
Part B:Answer=22. Remember, if you take any two distinct points on a line, the slope of the line will be equal to the average rate of change. In short, we're just looking for the slope between the ordered pairs (1,27) and (4,93). The formula for slope is:
The average rate of change between x=1 and x=4 is 22. The average rate of changed describes the rate at which miles is changing with respect the the change in hour.
Part C: Answer=10hours. Since by now we know both the slope and the y-intercept, lets write the equation in slope intercept form and then solve for 225 miles.
y=mx+b
y=22x+5
225=22x+5
subtract 5 from both sides
220=22x
divide both sides by 22
10=x
It would take 10 hours for the turtle to travel 225miles from it's nest.
