1. divide all sides by 24 to save time.
37=21-20x
2. subtract 21 this both sides
16= -20x
3. divide both sides by -20
-16/20 = x
4. reduce to its lowest terms
-4/5= x is the answer
Answer:
1) 25 miles
2) 20 m
Step-by-step explanation:
Number 1 is going to be
because it's a right triangle
So
+ =
625 =
c = 25 mile
Number 2 uses the same process, but changing to using C instead of A
a^2 = c^2 - b^2
a^2 = 625 - 225
a = \sqrt(400)
a = 20m
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle
