9514 1404 393

  D.  60%

Step-by-step explanation:

You can work multiple choice questions a number of ways. One of the most effective is to eliminate unreasonable choices.

Only two percentages are listed among the answer choices: 60% and 25%. You know that more than half of the lights were green, so the only reasonable choice is 60%.

__

If we assume lights are either red or green, then 4 of 10 red lights means 6 of the 10 lights were green. As a percentage, that fraction is ...

  6/10 × 100% = 60%

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
