The answer is B. If 1 kilogram is 1,000 grams and mary needs 2 kilograms of potatoes she would multiply 2 by 1,000 equaling 2,000.
Answer:
The answer to your question is z = -3
Step-by-step explanation:
Expand 42 = -7(z - 3)
42 = -7z + 21
Simplify 7z = -42 + 21
7z = -21
Clear z z = 
z = -3
Because BD is the angle bisector, and m∠ABC=40, m∠ABD is 20.
In case you'll need to find out x and y:
3x-1=34-2x, and 3y+6=5y-18
solve: 5x=35, x=7
2y=24, y=12
(m∠ABD=3x-1=3*7-1=20, again, the answer is in this case)
