Answer:
8090.54
Step-by-step explanation:
30.8*6.6*39.8
25a + 5b - 13
5(5a + b) - 13 is your answer
using the distributive property, we can distribute 5 to all terms within the parenthesis:
5(5a + b) - 13 = 25a + 5b - 13
5(5a) = 25a
5(b) = 5b
25a + 5b - 13 = 25a + 5b - 13 (True)

Note that m∠4 and m∠1 are vertical angles, and so they would have the same measurements (same for m∠3 & m∠2). Note that m∠1 and m∠2 are supplementary angles (going to have a total measurement of 180°)
m∠2 = 50° (given)
m∠1 + m∠2 = 180
m∠1 + 50 = 180
Isolate m∠1. Note the equal sign. What you do to one side you do to the other. Subtract 50 from both sides
m∠1 + 50 (-50) = 180 (-50)
m∠1 = 180 - 50
m∠1 = 130°
m∠1 = 130° is your answer

He completed 18 passes. Since he started out attempting 7 and then it went to 21, 21 divided by 7 is three. To then make it even on both sides you would need to multiply 6 but 3 in order to get the number of completed passes. You can also take the final answer, 18/21, and reduce it and find it is 6/7.
