Answer:
I don't understand what should i answer.
The only thing I undrestood was that this is a relation which can be a function.
So we cant go over $250
35+20n=250
now that i put the question in an expression we can take the 35 away from both sides
35+20n=250
-35. -35
_____________
20n=215
now divide 20 by both sides to get (n) alone
20n=215
________
20
n= 10.75
we round down because we cannot exceed the limit, thus
ANSWER: 10 months
Answer:
The length is 16 ft, and the width is 3 ft.
Step-by-step explanation:
Let L = length & let W = width.
The perimeter of a rectangle is
P = 2(L + W)
The area of a rectangle is
A = LW
We know the perimeter and the area, so we substitute those values int he equations above and we switch sides in both equations.
Perimeter: 2(L + W) = 38
Divide both sides by 2:
L + W = 19
Area: LW = 48
We have a system of two equations in two unknowns:
L + W = 19
LW = 48
Solve the first equation for L and substitute it into the second equation.
L = 19 - W
(19 - W)W = 48
19W - W^2 - 48 = 0
Multiply both sides by -1, and rearrange the order of the terms.
W^2 - 19W + 48 = 0
(W - 16)(W - 3) = 0
W - 16 = 0 or W - 3 = 0
W = 16 or W = 3
Use W = 3 to find L
L = 19 - W
L = 19 - 3
L = 16
Answer: The length is 16 ft, and the width is 3 ft.
Answer:
It's closer to 5 cuz 489.2/71.8 = 6.81337047
