Answer:
x=-5
Step-by-step explanation:
-3x+25=40. You want to isolate x so you have to subtract 25 from both sides. -3x=15. We then want x to be isolated so we have to divide both sides by -3 to make x by itself. x=-5. Therefore, x=-5.

y = 80x - 60
Answer is B. y = 80x - 60
Double check:
When x = 1, y = 80(1) - 20 = 80 -60 = 20
When x = 2, y = 80(2) - 20 = 160 -60 = 100
When x = 3, y = 80(3) - 20 = 240 -60 = 180
When x = 4, y = 80(4) - 20 = 320 -60 = 260
When x = 5, y = 80(5) - 20 = 400 -60 = 340

Answer: 3 x 10^6</h3>
This is the number 3,000,000 aka 3 million
=======================================================
To find this answer, we divide the two values (large/small)
(9 x 10^12)/(3 x 10^6)
(9/3) x 10^(12-6)
3 x 10^6
We divided the stuff out front like normal (9/3 turns into 3) and we subtract the exponents when dividing the 10^12 over 10^6. The general rule is that
(a^b)/(a^c) = a^(b-c)
The result 3 x 10^6 is in scientific notation. It represents the number 3,000,000 aka 3 million. While 9 x 10^12 represents 9,000,000,000,000 which is the number 9 trillion.
If consecutive angles of a 4-sided figure were complementary, then all four of them <span>would add up to 180°. But that's a problem, because we all know that the sum of all </span>four angles in any 4-sided figure is always 360°. So the answer must be: 'No<span>'.</span>
