Answer:
22.5
Step-by-step explanation:
10 x 4.5 = 45 divided by 2 is 22.5
Answer:
Step-by-step explanation:
Solve simultaneously
-5x-3y=9
4x-187-54=0
4x=241
x=60.25
To get y
Substitute for x in equal one
-5(60.25)-3y=9
-301.25-3y=9
-3y=9+301.25
-3y=310.25
y=-103.4
For this case we have to evaluate the following expression,
We must follow the steps below:
We convert the mixed number into a fraction:
We multiply the fractions, taking into account that:
We simplify:
We convert to mixed number:

<em><u>Answer</u></em>
c. It divides the radius by 2.
<em>Explanation</em>
The general equation of a circle is
(x-h)² + (y-k)² = r²
Where (h, k) makes the coordinates of the circle and r the radius.
x² + y² = 25 For this equation,
center (0, 0)
Radius = √25 = 5
4x² + 4y² = 25 First simplify this equation
4x² + 4y² = 25 ⇒ x² + y² = 25/4
center (0, 0)
Radius = √(25/4) = 5/2
The radius has been divided by 2
