Answer:
6
Step-by-step explanation:
Consider this option:
if new map is bigger 3 times then old one, it means that the new area is bigger 3 times then the old one. And if the area is 3 times bigger, the side is bigger √3 times.
Using the rules described above it is possible to calculate new scale of the map:
12*√3≈12*1.7=20.78461 yards in 1 inch.
If it is possible check the suggested solution in other sources.
I'm not 100% sure, but I believe the answer would be:
D. For every additional adult at the park, the number of children increases by about 7.
P.S. good luck on the 6.10, fellow classmate!
Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2
