Cross multiply
16x-48=12x
Subtract
4x=48
Divide
X=12
Answer:
$1200
Step-by-step explanation:
First we need to find 25% of 5,000, which is 5,000*.25=1250
Then we need to reduce 50 from 1250 which is 1250-50=1200.
Hope this helps!
Answer:
1/1
Step-by-step explanation:
graph the equation and than put it in a fraction of rise over run.
C is the correct answer!!
The perimeter in this case is:
y + 2x = 5000
The area is:
A = x * y
We rewrite the area:
A = x * (5000-2x)
A = 5000x-2x ^ 2
We derive:
A '= 5000-4x
We equal zero and clear x:
0 = 5000-4x
4x = 5000
x = 5000/4
x = 1250
We look for the other dimension:
y = 5000-2x
y = 5000-2 (1250)
y = 5000-2500
y = 2500
Then, the area will be:
A = (2500) * (1250)
A = 3125000 m ^ 2
Answer:
The largest area that can be enclosed is:
A = 3125000 m ^ 2
