For this case, the first thing we must do is define variables.
We have then:
x: amount of money for charity 1.
y: amount of money for charity 2.
We now write the system of equations that models the problem:
We solve the system.
Using substitution we have:
Clearing x:
Then, the value of the second charity is:
Answer:
charity 1 = $ 83500
charity 2 = 65500 $
Answer:
Step-by-step explanation:
( x² - 2 × 5 × x + 25 ) - 25 + 100 = ( x² - 5 )² + 75
Answer:
1.47
Step-by-step explanation:
Use the multiplication method.
Step-by-step explanation:
π= 3.14
Given
Circumference = 12.56 units
First calculating radius
so 2πr = 12.56
2 * 3.14 * r = 12.56
6.28 r = 12.56
Therefore r = 2 units
Now calculating Area
Area = πr²
= 3.14 * 2²
= 12.56 square units
Answer:
This can be a rhombus or a parallelogram.
