Answer:
C is correct
Step-by-step explanation:
-3(2b+9) + 5 (-5b+ 6)
-6b-27 -25b +30
-31b+3
A) Two parallel lines, intersecting a 3rd line (a traversal), indicates that two same-sided, internal angles MUST be SUPPLEMENTARY (sum, or add up to 180°).
b) Since <1 and <2 are supplementary, they add up to 180°. Therefore, <1 + <2 = 180:
(20x+5) + (24x-1) = 180
44x + 4 = 180
44x + 4 -4 = 180-4
44x = 176
44x/44 = 176/44
x = 4
I think it may be (10×-3)
0.49 is the answer to 7% of 7.000
