Answer:
b. All real numbers
Step-by-step explanation:
Simplify:
- 5(x-2) = (15x+6)/(3) - 12
- 5x - 10 = 5x + 2 - 12
- 5x - 10 = 5x - 10
- -10 = -10
- 0 = 0
Since both sides are equal to each other, any value of x makes this equation true.

Answer:
$5
Step-by-step explanation:
Just use simultaneous equations to solve this problem.
Let cost of pens = x and cost of pencils = y:
217 x + 131 y = 913
131x + 217y = 827
Solving these 2 equations you get: x = 2 and y = 3
Hence, cost of one pen and one pencil = 2 + 3 = 5 rupees
Answer:
8 - 8i
Step-by-step explanation:
w= 4 - 4i
w + w = (4-4i) + (4-4i)
= 8 - 8i
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.
