Answer:
1) The system of equations is and
2) The first number is and the second number is
Step-by-step explanation:
1) Let be "x" the first number and "y" the second number.
Remember that:
a- The word "times" indicates multiplication.
b- A sum is the result of an addition.
c- "Is" indicates this sign:
Then, the sum of 5 times "x" and 4 times "y" is 75, can written as:
And "The sum of the two numbers is 18" can written as:
Therefore, the System of equations is:
2) You can use the Elimination Method to solve it:
- Multiply the second equation by -5, add the equations and then solve for "y":
- Substitute the value of "y" into any original equation and solve for "x":
Answer:
Step-by-step explanation:
it is given that Square contains a chord of of the circle equal to the radius thus from diagram
If Chord is equal to radius then triangle PQR is an equilateral Triangle
Thus
In triangle PQO applying Pythagoras theorem
Thus length of Side of square
Area of square
Area of Circle
Ratio of square to the circle
