Answer:
BC = 30
Step-by-step explanation:
If the three points are collinear, it means they lie on the same straight line.
Now B lies between A and C
By mathematical convention;
AC = AB + BC
This means;
48 = 2x + 2 + 3x + 6
48 = 5x + 8
48-8 = 5x
5x = 40
x = 40/5
x = 8
From the question BC = 3x + 6
Substitute the value of x; 3(8) + 6 = 24 + 6 = 30
Answer:
Sam made a mistake, and their correct value is 30.
Step-by-step explanation:
Answer: x = 5
Step-by-step explanation:
Want me to show this, or did you just want the answer?
For this case we must find the value of n of the following equation:

Taking common factor "n" from the left side of the equation we have:

Multiplying by 5 on both sides of the equation:

Dividing between 6 on both sides of the equation:

Thus, the value of n is 20.
Answer:

Answer:
1/8
Step-by-step explanation:
<u>Solving in steps:</u>
- x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
- x/8(x-y) +y/8*(-(x-y))
- x/8(x-y) - y/8(x-y) =
- (x -y)/8(x-y) =
- 1/8
Answer is 1/8
