Answer:
2n + 5 = 8
Step-by-step explanation:
If you subtract n from 3n, you are left with 2n.
Since you are subtracting one n, it would be like subtracting 1 from 3.
3 - 1 = 2
Hence, The answer would be 2n + 5 = 8
(Hate to be that person, but if it helped, please give me brainliest.)
Cyaa ^^
I^3=-i
therefor -27i=(3i)^3
so we can get a sum of 2 perfect cubes
a^3+b^3=(a+b)(a^2-ab+b^2)
so
remember that i²=-1
x^3+(3i)^3=(x+3i)(x²-3xi-1)
Answer: 1100
Step-by-step explanation: mark x for the total sum.
0.35x+ 0.20x + 495 = x. 495= x-0.35x-0.20x
495= 0.45x. X= 495/0.45
Answer:
ΔDAE
Step-by-step explanation:
Complementary = 90°
ΔBAC has a right angle, which makes it 90°. Since ΔDAE also has a right angle, it would be complementary to ΔBAC.
Answer:
1) First, add or subtract both sides of the linear equation by the same number.
2) Secondly, multiply or divide both sides of the linear equation by the same number.
3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.
