Answer:
x = 149
Step-by-step explanation:
Lines m and n are parallel lines as shown by the double arrows on each line.
The angles marked x and 149 deg are corresponding angles of parallel lines cut by a transversal.
<em>Postulate:</em>
<em>If parallel lines are cut by a transversal, then corresponding angles are congruent.</em>
According to the postulate above, since the angles marked 149 and x are corresponding angles, they are congruent.
x = 149
Answer:
(-8, -2)
Step-by-step explanation:
Combine these equations: You'll get 2y = -4, so that y = -2.
Substituting -2 for y in the second equation, you'll get -2 + x = -10, or x = -8
Thus the solution is (-8, -2)
Answer:
it is slightly less than 12
Step-by-step explanation:
To find the unit rate, 391/17 gives us 23$ per hour time 13 hours is 299$ total.
Cycling = 69 - (32 + 27) = 69 -59 = 10
Badminton = 62 - (32+28) = 62 - 60 =2
Archery = 63 - (27 + 28) = 63 - 55 = 8
Total for 1 sport = 10 + 2 + 8 = 20
Pupils left = 120 - 20 = 100
Pupils that picked two sports = 27 + 28 + 32 = 87
Number of pupils to pick all sports = 100 - 87 = 13
13 pupils picked all three
