Answer:
Step-by-step explanation:
First one is 0.066 cents and the second is is 15.266 dollars
X ·2 = 12x - 15
2x = 12x - 15
2x + (-12x) = (12x - 15) + (-12x)
Result: x = 3/2
Answer:
[4, -1]
Step-by-step explanation:
Using the Elimination Method:
3x + y = 11
5x - y = 21
__________
8x = 32
__ ___
8 8
x = 4 [Plug this back into both equations to get the y-coordinate of -1]; -1 = y
The <em>y</em>'s are already <em>additive</em><em> </em><em>inverses</em><em> </em>[result in 0], canceling each other out.

Answer: 20/4.
Step-by-step explanation: As we can see, the number line is cut up into fourths. 4 fourths make a whole, so 20 fourths make 5. Therefore, 5 in a fractional form for this number line is 20/4.
Have a great day! :)
