Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
Answer:
6, 11, 16, 21
Step-by-step explanation:
To obtain the first 4 terms add the common difference 5 to the previous term, that is
a₁ = 6
a₂ = a₁ + 5 = 6 + 5 = 11
a₃ = a₂ + 5 = 11 + 5 = 16
a₄ = a₃ + 5 = 16 + 5 = 21

Step-by-step explanation:
Answer:
m = -4.33333 or -4 and 1/3
Step-by-step explanation:
gradient = (difference in y)/(difference in X)
m = (-1-12)/(8-5)
m = -13/3
m = -4.3333333

Answer:
$7.10
Step-by-step explanation:
Nevach's rate can be found by using x=1 in the equation for his pay.
y = 28.5 × 1 = 28.50 . . . . dollars
Carson's hourly rate can be found by dividing dollars by hours:
$214/(10 h) = $21.40/h
Nevach's rate exceeds this by ...
$28.40 -21.40 = $7.10
Nevach earns $7.10 more per hour.
