Answer:
20°
Step-by-step explanation:
According to the question, pair of supplementary angles are x and 8x
since they are supplementary, their sum is equal to 180°
x+ 8x = 180°
9x= 180°
x= 180°/9
x= 20°
Answer:
(-5,7)
Step-by-step explanation:
When we move from (-5, -8) to (-7, -6), we move -2 units across the x axis to get from the 1st to 2nd point, and we move -2 units across the y axis to get from the 1st to the 2nd point. So, just subtract -3 by 2 and 9 by 2 to get -5 and 7.
Joshua used the Commutative Property.
You can change the order of the numbers you are adding because they will equal the same answer.

Answer:
100 children
150 adults
Step-by-step explanation:
c- children
a- adults
---------------
we get equations as per question:
- 1.5c+4a= 750
- c+a= 250 ⇒ a= 250- c
- 1.5c +4(250-c)= 750 ⇒
- 1.5c- 4c+1000=750 ⇒
- 2.5 c= 250 ⇒
- c= 100
- a= 250-100 ⇒
- a= 150
Children 100, adults 150
