No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.

The circle area formula is A=pi r^2. I am assuming those numbers represent diameter, and diameter is radius x 2. 6/2=3, and pi 3^2= 28.27433388. Divide this by 2 and the area of your half circle is 14.13716694. On the other half circle, 5/2= 2.5. pi times 2.5^2 is 19.63495408, divided by two is 9.817477042. Hope it helps!
Answer:
The total cost is $95.32.
Step-by-step explanation:
Given:
Total came to $76.75. There is an 8% sales tax and 15% tip.
Now, to find the total cost.
<em>8% sales tax is there so we calculate the amount after adding sales tax:</em>
$76.75 + 8% of $76.75
The cost after sales tax is $82.89.
Now, <em>the cost after 15% tip:</em>
$82.89 + 15% of $82.89
The cost after the tip is $95.32.
Therefore, the total cost is $95.32.
