Answer:
<u>Ravi</u> and <u>Courtney</u>
Step-by-step explanation:
<u>Simplifying the equations</u>
<u>Penny</u>
<u>Ravi</u>
- 2x + 3y = 3
- 3y = -2x + 3
- y = -2/3x + 3
<u>Courtney</u>
- -4x - 6y = -6
- 6y = -4x + 6
- y = -2/3x + 3
<u>Edwin</u>
- 6x + 6y = 9
- 6y = -6x + 9
- y = -x + 9
<u>Ravi</u> and <u>Courtney</u> would have infinitely many solutions because they are the same equation.

Answer:
65 in²
Step-by-step explanation:
1. Break up the figure (We'll do it left to right): We now have 3 rectangles:
<em>(6 - 4) x 4, (4 + 8) x 4, and 3 x 3</em>
2. Find the two lengths: 6 - 4 = <em>2</em>, 4 + 8 = <em>12</em>
3. Find the three areas: 2 * 4 = <em>8</em>, 12 * 4 = <em>48</em>, 3 * 3 = <em>9</em>
4. Add the areas: 8 + 48 + 9 = 65 in²
Answer:(5•X)+9=11
Step-by-step explanation:
336 inches is bigger because if you convert 18 ft into to inches it would be 216 in
which is less than 336
