the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

answer: math isn’t just mysterious because the majority of us find it so difficult to understand – it’s also the basis of the universe, giving us clues to physical phenomena like the motion of gases in the atmosphere and the way that physical particles interact with each other amid all the possible variables in three-dimensional space.

part a.

angle addition postulate:

if a point lies on the interior of an angle, that angle is the sum of two smaller angles with legs that go through the given point.

from the diagram you can see that point w lies on the interior of an angle, then

m∠uvx=m∠uvw+m∠wvx.

answer: correct choice is b.

part b.

substitution property of equality:

if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.

given that xy≅yz and xy=4a+4, yz=20, you can substitute instead of xy the expression 4a+4 and instead of yz the expression 20 into the iquality xy≅yz and obtain

4a+4=20

answer: correct choice is a.
