Step-by-step explanation:
Using the Section formula, then
=
=
=
= 6
=
=
=
= 12

Answer:
$2
Step-by-step explanation:
x = daylily
y = geranium
1x + 5y = 22
13x + 1y = 30
Multiply second equation by 5 and subtract the two equations.
1x + 5y = 22
- (65x + 5y = 150)
-64x = -128
x = 2
So one daylily costs 2 dollars
Subtract the new amount from the original amount:
64 - 85 = -21
Now divide that by the original amount:
-21 / 85 = -0.247
Multiply that by 100 for the percentage:
-0.247 x 100 = -24.7%
Rounded to the nearest percent is -25%
Answer:
b. 0.38.
Step-by-step explanation:
