Answer:
The solution is x = 1 because 2(1) - 1 = -1
Step-by-step explanation:
Answer:
One number is 4.2, the other is 18.8
Step-by-step explanation:
1.) x+y=23
(x+6y)x2=4
2.) (x+6y)x2=4 = 2x+12y=4
3.)Use elimination/substitution to solve
2x+12y=4 = x+6y=2 = x=2-6y
2-6y+y=23
4.)Solve for y
2-5y=23 -> -5y=21 -> y=4.2.
5.)Solve for x
x+4.2=23
x=18.8

Answer:
To figure what?
It doesn't show anything?
Answer:
A) 125.6 inches
Step-by-step explanation:
1. The radius: As you said, it is half the diameter, so it is 40/2, which is <em>20 inches</em>.
2. Plug in numbers into the equation: r = 20 inches, π = 3.14
<em>C = 2 * 3.14 * 20 inches</em> (of course, it was unnecessary to find the radius when we already have the diameter, but this was done to fit the given equation)
Multiply: C = 125.6 inches
