Answer:
40 children went on the cruise.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of adults on the cruise
y is the number of children on the cruise.
57 tickets were sold:
This means that 
, and since we want the number of children y, 
Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.
This means that:
Since
40 children went on the cruise.
6/2 Changed into a unit rate is 3/1 so joan can mow 3 acres in 1 hour
Answer:
(0,7) and (-4,7)
(-2,3) is vertex
Equation is (X+2)2+3
When x = 0, y = 7 and when x = -4, y = 7
counterclockwise 90 degrees
Answer:
8
Step-by-step explanation:
Well since the 55 degrees is the same as the equation. First I subtracted 55 by 15 which i got 40 then since the 5 and x are next to each other I divided that by 5 and got 8.
Hope this helps!
