Answer:
P = 32
x = 35
Step-by-step explanation:
For the first diagram,
The two angles given are corresponding angles. Corresponding angles are equal;
So;
the first angle is a right angle triangle;
90 = 3P - 6
3P = 90 + 6
3P = 96
P = 32
For the second diagram;
The sum of those two angles is 180°
(x + 75) + 2x = 180
x + 2x + 75 = 180
3x + 75 = 180
3x = 180 - 75
3x = 105
x = 35
Say Terry read at the rate of 75 pages per day for d days.
Now, in d days she read 75d pages, and since after that 690 pages were left, then the number of pages in the book is 75d+690.
Next, we also know that she had d+6 days for the assignment. Since Terry planned to read 90 pages per day for this number of days, then the number of pages in book is also equal to 90(d+6).
So, we have that 75d+690 = 90(d+6). Solving the linear equation, we get d = 10.
Thus, the total number of days that she has to complete the assignment on time is d+6 or 10 + 6 = 16 days.
Answer:
friend correct answer is 4/13
Answer:
D. Marcus rent a car for 5 days
Step-by-step explanation:
You can solve this by simply plugging the answer choices into the variable d for both equations and comparing the total costs.
When you plug in 5 days you get:
Plan A
C = 30 x 5
C = 150
Plan B
C = 25 x 5 + 15
C = 140
The cost is less for Plan B in this case, so it is better to use Plan B when renting for 5 days.
