question:  

the chart compares religious beliefs to us political party support.

religious beliefs and party support, 2012

this chart demonstrates that

a) more highly religious people supported the republican candidate, while more nonreligious people supported the democratic candidate.

b) more highly religious people supported the democratic candidate, while more nonreligious people supported the republican candidate.

c) more moderately religious people supported the republican candidate, while more nonreligious people supported the democratic candidate.

d) more moderately religious people supported the democratic candidate, while more nonreligious people supported the republican candidate.

answer: a.

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
