You can write it as 454 kg in 3 significant digits.
The answer is either $61.62 or $12.72
Answer:
x = 4
Step-by-step explanation:
6x - 8 = 4x
<em>subtract 4x from both sides of the equation</em>
6x - 4x -8 = 4x - 4x
2x - 8 = 0
<em>add 8 to both sides of the equation</em>
2x - 8 + 8 = 0 + 8
2x = 8
<em>divide both sides of the equation by 2</em>
2x/2 = 8/2
x = 4
Answer:
x=2
Step-by-step explanation:
1/2x+3=5/2x-1
1/2-5/2x=-1-3
-4/2x=-4
-2x=-4
x=-4/-2
x=2
I'm sure there's an easier way of solving it than the way I did, but I'm not sure what it could be. Never dealt with a problem like this before.
Anyway, I just plugged in and tested. Chose random values for a, b, c, and d, which follow the rule 0 < a < b < c < d:
a = 1
b = 2
c = 3
d = 4


Simplify into standard form:



Use the quadratic formula to solve:

For functions in the form of

. So in this case:
a = 1
b = -4
c = 2
Plug them in:

Solve for 'x':




So the answer would be A.
