Answer:
Step-by-step explanation:
7g-6+3n+4= 7g+3n-2
Answer: 1
Step-by-step explanation:
First you need to multiply 3 x 3 (9), because that's all 3 squared means.
Now the equation should be 9x-6x+3=0
Next we need to combine like terms. Do 9x - 6x which should give you 3x
Now your equations should be 3x+3=0
Now for the somewhat harder part...
Under the three (the one without the x) write -3 and under the zero write the same thing. the +3-3 cancels out so just put a line or something across it.
0-3= -3
so now you should have...
3x=-3 ignore the 3x, at this point it's useless in getting the answer because it would cancel out.
-3 divided by -3 is 1 because a negative (-) divided by a negative (-) equals a positive (+).
The answer should be x = 1
Answer:
the first draw will be 2/18 the second one will be 2/17
0.003km=3m=300cm=3000mm
So 0.003km, 300cm and 3000mm are equivalent to 3 meters
11a) You can see for yourself that the change in distance vertically is 8 and that horiz. is 6. Thus, the distance between (1,6) and (7,-2) is
d = sqrt(6^2 + 8^2) = sqrt(36+64) = 10 units (answer)
