Answer:
Try to find the value for B/A if the value of B/A is the same for each pair of numbers
Step-by-step explanation:
Steps to determine if two quantities in a table are proportional to each other: For each given measure of Quantity A and Quantity B, find the value of B/A If the value of B/A is the same for each pair of numbers, then the quantities are proportional to each other.
They would cost $8.75. If you take out 30% from the original price, that is how much they would be.
Step-by-step explanation:
x= Number of small pages
y= Number of full pages
1 x + 1 y = 21 .............1
Total words
1200 x + 1500 y = 27000 .............2
Eliminate y
multiply (1)by -1500
Multiply (2) by 1
-1500 x -1500 y = -31500
1200 x + 1500 y = 27000
Add the two equations
-300 x = -4500
/ -300
x = 15
plug value of x in (1)
1 x + 1 y = 21
15 + y = 21
y = 21 -15
y = 6
y = 6
x= 15 Number of small pages
y= 6 Number of full pages
Answer:
x=-3 y=-5

The area of the shaded region is the square subtract the circle. The radius of the circle is the diameter/2
Area of circle= pi x radius x radius
=3.14 x 5 x 5 = 78.5
Area of the square = side x side
= 10 x 10 = 100
Area of shaded 100 - 78.5 = 21.5
And don’t forget the unit of measurement (meters)
