<span>6x+9y = 10500
x+y = 1480
Using elimination I get:
6x + 9y = 10500
-6x-6y = -8880
Add the 2 equations and I get 3y = 1620
Divide both sides by 3 and I get y = 540
Substitute that back in to 6x+9y = 10500.
I get that 6x+9*540 = 10500
9 * 540 = 4860
Subtract 4860 from both sides and I get 6x = 5640
Divide both sides by 6 and I get x = 940
So there must have be 940 children and 540 adults</span>
I believe the answer is (a+c, b) but I'd double check to make sure.
Answer:
304.85 cm²
Step-by-step explanation:
The area (A) of a polygon is calculated as
A = pa ( p is the perimeter and a the apothem ) , thus
A = 45.5 × 6.7 = 304.85 cm²
