Answer: x = 17
Step-by-step explanation: combine all of those numbers.
3x+x+22.
Combine like terms, so
4x + 22 = 90 (90 is the sum of 2 complementary angles)
Subtract 22 from both sides to get
4x = 68
Now divide by 4 to get x which is
x = 17
(3 x 10^6)(8 x 10^-4) = (3 x 8) x 10^(6 - 4) = 24 x 10^2 = 2.4 x 10^3
I believe it’s 27 if it’s not right let me know but I believe that’s the correct answer! :D
