I think it’s 3 but I’m not sure
Answer:
K= 11
Step-by-step explanation:
You solve for K by subtracting 14 by 25.
25-14= 11
When k is pluged into k
11 the statement is true because it is equal to 11.
When plugged into k+14
25;
11+14 =25.
That statement is also true because 25 is equel to 25.
A little Algebra, and we're home free!
We are given R = 20 and r2 = 75. We need to find r1.
The formula is 1/R = 1/r1 + 1/r2. Plug-in:
1/20 = 1/r1 + 1/75
1/20 - 1/75 = 1/r1
0.0366 = 1/r1
r1 = 1/0.03666
r1 = 27.272
Our answer is r1 = 27 ohms.
Answer:
C) x=35
Step-by-step explanation:
First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:
4x + 2(3x+5) = 360
By now using our linear equation skills, we get:
10x+10=360
10x=350
x=35
The degree amount of x for c) is 35 degrees.
In order to solve this i'd have to know what x equals?? does it tell you?
