Jana has a rectangular sheet of cardboard that measures 10 inches by 18 inches. what is the maximum number of 3*3 inch squares that she can form out of this cardboard?
a: 15 b: 17 c: 18 d: 19 e: 20

C

Step-by-step explanation:

The 10 inch sides will produce 10 / 3 = 3 squares and 1 inch left over.

The 18 inch sides will produce 18/3 = 6 squares with nothing left over.

The number of squares is 3 * 6 = 18

C

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.
