Answer:she spent 10 hours working in her aunt's store last week.
Step-by-step explanation:
Let x represent the number of hours that Lee spent working at the movie theater.
Let y represent the number of hours that Lee spent working at her aunt's store.
Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that
x + y = 30
Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that
9x + 6y = 240 - - - - - - - - - -1
Substituting x = 30 - y into equation 1, it becomes
9(30 - y) + 6y = 240
270 - 9y + 6y = 240
- 9y + 6y = 240 - 270
- 3y = - 30
y = - 30/ - 3 = 10 hours
The equation that gives the line is A.
Step-by-step explanation:
Step 1:
First, we need to plot some points on the line on the graph. Some of the points are (1, 55), (3, 65), and (3, 75).
We need to find which of the given equations relating the x values to the values of y in the determined coordinates.
y is the dependent value whereas x is independent i.e. the y value changes according to the x value.
Step 2:
Now we substitute the values in the given equation to see which corresponds correctly.
For , when x = 2,
For , when x = 2,
For , when x = 2,
For , when x = 2,
Only the first equation gets a value of y, that corresponds to a coordinate on the line of the graph, so A. represents the line of best fit.
Answer: (B) - 55
Explanation: We have a hexagon, albeit irregular.
Since it is a six-sided shape, we know that the angle sum of a hexagon is 720°, using the angle sum formula, 180 · (n - 2), where n represents the number of sides.
Thus, we can say that the angles have to add up to 720°
Now, we know the missing side inside the hexagon has to be (180 - x), since x and the missing angle join to make a straight line (in other words, they are supplementary).
Now, we can say:
(180 - x) + 115 + 130 + 115 + 130 + 105 = 720
775 - x = 720
-x = 720 - 775 = -55
x = 55
