Answer:
29
Step-by-step explanation:
-18 (Negative Eighteen) = A
29 (Positive Twenty Nine) = B
11 (Positive Eleven) = C
First, make A positive, and add C to it. You get B.
Now here is the equation:
-18 + (18 + 11)
-18 + (29)
11
-3w-5(4x-4w)-4x
multiply the bracket by -5
(-5)(4x)=-20x
(-5)(-4w)=20w
-3w-20x+20w-4x
-3w+20w-20x-4x ( combine like terms)
answer:
17w-24x or -24x+17w
1. 2.6
2. 0.9
3. 4.5
if you count the lines on the ruler, you can find the answer
Reason 2 is that they are linear, so they form 180 degrees, which makes them supplementary. Reason 3 is that they are both 180 - angle 3. I think. I'm not sure about reason 3.
