Answer:
A) 5x-6y=3
B) 7y=2x+8
B) -2x + 7y = 8 then multiplying "B" by 2.5
B) -5x +17.5y = 20 then adding this to A
A) 5x -6y = 3
11.5y = 23
y = 2
x = 3
Step-by-step explanation:
The area of d=8in would be A=50.27 squared inches!
a. When v = c, then v^2 = c^2. The fraction v^2/c^2 becomes 1. The inside of the root is 1 - 1 which equals zero. Square root of zero is zero, and zero times L0, no matter what value L0 has, is zero. Therefore, when v = c, the left side equals zero.
b. When v = 0, and c is positive, v/c = v^2/c^2 = 0. By subtracting v^2/c^2, which is zero for v = 0, from 1, you get 1. Square root of 1 is 1. Then you multiply that by L0 to get L0. The greatest possible value of the left expression is L0.
Answer:
615.44
Step-by-step explanation:
If diameter = 28, then radius is 14
Area = 3.14 x (14x14) =615.44
ANSWER: 3,520 yards = 2 miles.
440 yds is 1/8. Multiply 440 by 8 to get the full distance. Hope this helps! :)
