divide the KM speed with 1.61 because 1 mile equals 1.61 KM
x => Hamburgers
y => Hot dogs
x + y = 26
3.5x + 2y = 70
-2x - 2y = -52
3.5x + 2y = 70
-----------------------
1.5x = 18
x = 18 / 1.5 = 12
y = 26 - 12 = 14
They sold 12 hamburgers and 14 hot dogs

Step-by-step explanation:
<u>Step 1: Define</u>
-9x + 1 = -x + 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 9x on both sides: 1 = 8x + 17
- Subtract 17 on both sides: -16 = 8x
- Divide 8 on both sides: -2 = x
- Rewrite: x = -2
Hold on let me try to help let me figure it out for you
It’s a semicircle, so it would be 1/2 pi r^2.
