I think it's add 6x to 54x..
X - rows of corn,
y - rows of lettuce:
x = 2.5 y
x + y = 455
------------------
2.5 y + y = 455
3.5 y = 455
y = 455 : 3.5
y = 130
x = 2.5 * 130 = 325
Answer: The farmer plans to plant 325 rows of corn and 130 rows of lettuce.
Answer:
Let's represent pink flowering plants with the variable p:
8p + 5(15 - p) = 96
8p + 75 - 5p = 96
3p = 21
p = 7
Step-by-step explanation:
Arianna bought 7 pink flowering plants
The original equation:
Integral of csc(5x)
Use a u sub:
u = 5x
du = 5dx
Simplify the du:
Apply to the equation:
Integral csc(u)
du
Simplify:
Integral
du
Factor out the constant:
Integral
du
Use a second Substitution:
v = tan(
)
du =
dv
Applying to the equation:
Simplify:
Integrate:
Insert back in your v and u:
v = tan(
)
u = 5x
This gives us the final equation (don't forget your constant):
(Thank you for making me write it out, I made a mistake on the original answer.)
