Answer:
20 x 12=240
Step-by-step explanation:
Answer: Yes it is true. We can write an equation by setting an expression equal to itself.
Step-by-step explanation:
Let we take an expression say 2x.
Since we know that any expression is equal to itself, so we can write it as 2x=2x, which does not give any solution or we can say this equation has no solution but we can not say it is false because they are actually equal.
Therefore, we can write an equation by setting an expression equal to itself. It would be a true equattion.
ANSWER:
As they are alternate exterior angles, so they must be equal.
8x + 13 = 12x + 7
8x - 12x = 7 - 13
- 4x = - 6
x = 3/2.
just add the whole numbers and add negative infront -16+-27= -43
