Answer:
12x+3x+1 = 15x+1
8r+2+2+-3 = 8r+1
8p+7-p+1 = 7p+8
4xy+17+14xy-xy = 17xy+17
11+4-2b+8b = 15+6b
Step-by-step explanation:
Did the best I could.
Answer:
41.4 is the answer
Step-by-step explanation:
<BAC is 35 because "the exterior angle of a triangle is equal to the sum of the interior angles at the other two vertices" or 180-120= 60 so <BCA is 60 and angles in a triangle add to 180 so 180-(85+60)=35
Answer:
identification from the table given below. use y = mx + c to solve
Step-by-step explanation:
y = 3x to third
y = 1.5x -7 to second
y =7 to first
y = -1.5x-4 to fifth
y = -3x+4 to fourth
