8o+12y=362
12o+8y=388
Im choosing “o” for orchid and “y” for lily
20o+20y=750
20o=750–20y
o=37.5–y
(37.5–y)+20y=750
-y+20y=712.5
19y=712.5
y=37.5
So, lilies sell for $37.50
Plug in 2 for x, and -4 for y
2(2)² + 3(2)(-4) - (-4)²
2² = 4(2) = 8
3(2) = 6(-4) = -24
-4² = 16
8 - 24 - 16 = answer
Simplify.
answer = 8 - 40
answer = -32
-32 is your answer
hope this helps
Since a total of 55 people rated it good/very good, we know that 1/3 of the viewers are 55 people. So we can set the equation: 1/3x=55
Now, just multiply both sides by 3 (or divide by 1/3, same thing) and get your answer!
