Kelly read 40% of a novel, and she now has 108 pages left. How many pages does the novel have?
Answers
Answer:
The novel has 180 pages.
Step-by-step explanation:
108 pages is 60% of the novel.
108 / 3 = 36.
20% of the novel is 36 pages.
36 * 5 = 180 pages

Okay, let's see...
The problem is asking for a linear equation most likely in the form of y=mx+b
y is another way to say f(x)
m = slope
b = y intercept
Let's start with the y intercept first.
Y intercept means ' When does the line touch (intercept) the y axis.
In this case, if you look at the graph, the line touches the y axis at -1.
-1 will replaces b
To find the slope we are going to take 2 precise points from the graph.
Lets use (0,-1) and (-6,4)
To find the slope, we're going to use
4 - (-1) / -6 - 0
Solve, our slope is 5/-6
That is our m
Our final equation is

Part A: Using the graph above, create a system of inequalities that only contains points A and E in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points)
Part B: Explain how to verify that the points A and E are solutions to the system of inequalities created in Part A. (3 points)
Part C: William can only attend a school in his designated zone. William's zone is defined by y < −x − 1. Explain how you can identify the schools that William is allowed to attend. (2 points)

First, we choose the lines...
y = -x + 2 has C and F above it and all other noted points below it. y = -x + 9 has all the points below it on the graph.
So if we include all points above the first line and all points below the second line, we obtain our intersected shaded area. To do this changes our linear equations to linear inequalities.
All points above y = -x + 2 would then be y > -x + 2
All points below y = -x + 9 would then be y < -x +9
Part B: Verify that these points satisfy the system of inequalities by substituting (x, y) for both points into both inequalities. [Pick any random point outside this shaded area to prove that it coordinates do not satisfy the system.]
Graph the line y = -2x + 2. That will be a line that has a y-intercept of 2 and a slope of -2. Then shade *below* that line (we shade below because it is y < ...). The schools that will be in the shaded region are B, A, and D.

For this case we have 18 yellow flowers and 30 white flowers, we must find a number that represents the largest number of groups of flowers that can be formed, bearing in mind that each group must contain the same number of yellow and white flowers. To do this, we must find the GCF (Greatest Common Factor) of yellow flowers and white flowers.
We look for the factors of 18, that is, the numbers for which 18 is divisible, these are:
18, 9, 6, 3, 2 and 1
We look for the factors of 30, that is, the numbers for which 30 is divisible, these are:
30, 15, 10, 6, 5, 3, 2, 1
Thus, we can see that GCF of both numbers is 6.
Then we can form 6 groups of flowers. To know the amount of flowers of each color in each group, we divide:
Thus, 6 groups of flowers can be formed with 3 yellow flowers and 5 white flowers each.
Answer:
The largest number of groups that can be done is 6.
Answer:
She can make 6 number of group.
Step-by-step explanation:
Given : Emma has 18 yellow flowers and 30 white flowers.
To find : What is the largest number of groups she can make.
Solution:We have given that
yellow flower = 18
White flower = 30
we nee to find the GCF (Greatest Common Factor) of yellow flowers and white flowers.
Factors of 18 are:
18, 9, 6, 3, 2 and 1
Factors of 30 are:
30, 15, 10, 6, 5, 3, 2, 1
Thus, we can see that GCF of both numbers is 6.
Then we can form 6 groups of flowers.
Thus, 6 groups of flowers can be formed with 3 yellow flowers and 5 white flowers each.
Yellow flower = = 3
White flower = = 5
Therefore, She can make 6 number of group.
