Answer:
x=20
Step-by-step explanation:
It all equals 360º and there are two of each angle. So, we can add 5x+5x+(3x+20)+(3x+20)=360º. Subtracted 40 and simplify. So 16x=320.So divide by 16 and you get that x=20.
The current grading rate is
(30 minute)/(5 papers) = 6 minutes/paper.
She has 3 hours (or 180 minutes) to grade 35 papers.
She now has 180 - 30 = 150 minutes left, and she has 35- 5 = 30 papers left.
The remaining grading rate is
(150 minutes)/(30 papers) = 5 minutes/paper
Therefore she must work at 1 minute/paper faster to complete grading 35 papers in 3 hours.
Answer: She should work faster at an increased rate of 1 minute per paper.
Answer:
Follows are the solution to this question:
Step-by-step explanation:
Given:
All points are on the graph including its quadratic function, in order to install their coordinates to values of x and y with the following values:
Inserting the coordinates of the first point
Inserting the coordinates of the second point
Inserting the coordinates of the third point
So it can be written as 2x + 5 = 11, and x = 3
