Answer:
x = 18
Step-by-step explanation:
Total interior angle of pentagon: 540 degrees
(3x + 23) + (9x - 6) + 95 + 90 + (7x - 4) = 540
19x + 23 - 6 + 95 + 90 - 4 = 540
19x + 17 + 95 + 90 - 4 = 540
19x + 13 + 185 = 540
19x + 198 = 540
19x = 342
x = 18
I THINK there is a typo. Instead of "for problems each day", i think it's "four problems each day."
Anyway, we need to find how many days it takes Jeremy to complete the paper.
If he completes 8 problems on the first day and 4 on the rest of the days, after the first day he'll have 28 - 8 = 20 more problems.
And since he does 4 every day with 20 problems: 20 / 4 = 5 days.
The given function has Amplitude of 3, and by seeing it we can conclude that it's a sine function.
Therefore, we can conclude that the required Answer is ~
It only has symmetry about the axis, that means that if i were to draw a line down the middle, the triangle looks the same on both sides. If it were split in half horizontally, it would not be symmetrical.
Yes, because adding 50 and subtracting 50 is equal to 140+50-50.
+50-50=0
Now, you have 140+0=140.
Hope this helped☺☺
