Answer:
Area = 126
Step-by-step explanation:
To figure out the area of the triangle, we must do 1/2 base times height. Which would be 1/2 of 6 times 6. Which is 18. Then to figure out the rectangle is just doing the width times the length and the same for the square. So 6 times 12 plus 6 times 6 equals 108. Then we add the triangles area and we come out with 108 plus 18 which equals 126.
Answer:
13
Step-by-step explanation:
there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.
hope this helps :))
x+y= 4 (-2)
3x+2y = 9
-2x -2y = -8
3x +2y = 9
x = 1
1+y =9
y = 9-1
y =8
If you want to find the cost per adult if 8 of them buy tickets for a total of $66, you would divide the total cost by the number of tickets bought. So, $66 divided by 8 would equal to $8.25 per ticket.
