What’s the question and I would be glad to help
Answer:
c = 30
Step-by-step explanation:
Given:
a + b = 150
As the triangle is a right angled triangle,
a + 90 = 150
a = 60
Hence, from angle sum property,
a + b + c = 180
150 + c = 180
c = 30
Answer:
375
Step-by-step explanation:
"817 tickets were sold"
a and s are the number of adults and students, respectively.
a+s = 817
s = 817-a
"67 more student tickets sold than adults"
s = a+67
817-a = a+67
750 = 2a
a = 375
Answer: 45 items
Step-by-step explanation:
2 key chains in 5 bags so 2+2+2+2+2=10
Then it says 7 treats in each 5 bags so
7+7+7+7+7=35
So 10+35=45 so she had 45 items
And put 9 items in each bag
Answer:
-2
Step-by-step explanation:
(1 , 3) = (x1 , y1)
(-2 , 9) = (x2 , y2)
slope = y2 - y2/x2 - x1
=9 - 3/-2 -1
=6/-3
=-2
