7y - 23 + 23x -16 + 8x - 21
31x + 7y - 60
What is the original problem equal to? You can't go any further unless you know.
Answer:
False
Step-by-step explanation:
Multiply 8 by 2 to create the common denominator (which is 16).
Now multiply 4 by 2 to keep the fraction even.
This gives you the fraction 8/16 which is not equivalent to 10/16.
Another way you could write this inequality:
8/16 < 10/16
Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).
Answer:
<u>The area of the circular garden is 28.3 square feet</u>
Step-by-step explanation:
Let's recall that the area of a circle is π * r², therefore if the diameter of the circular garden is 6 feet, the area is:
Diameter = 6 feet ⇒ radius = (6/2) = 3 feet
Area of the circular garden = π * 3²
Area of the circular garden = 3.1416 * 9
Area of the circular garden = 28.2744
<u>Area of the circular garden = 28.3 square feet</u>
