Answer:
24 right handed students
Step-by-step explanation:
1. Out of every 5 students, 4 are right handed and 1 is left handed. We can say that 1/5 of the class is left handed.
2. Multiply 30 by 1/5 to get 6 left handed students in the class.
3. Take the 30 students in the class and subtract the 6 left handed students.
4. The remaining 24 students must be right handed.

The area of a shape is the amount of space the shape can occupy.
The dimension that maximizes the design is 20 inches by 20 inches
From the question, we have:
Let the length and width of the graphic (without the margin) be l and w.
So, the dimension of the whole graphic is:
The area is then calculated as:
Substitute
Make l + 4, the subject
Subtract 4 from both sides
The area of the design is:
So, we have:
Plot the graph of
From the graph (see attachment), the maximum is at:
Substitute in
Divide both sides by 20
Hence, the dimension that maximizes the design (<em>excluding the margin</em>) is 20 inches by 20 inches

Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for a linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
