He did this then that plus to this and that =334.2
That diagram can be split into a right angled triangle of base 7 and of height 4 + 5.2 + 2 = 11.2, and a square of length of 5.2 So the are of the total shape is the area of the right angled triangle + the area of the square.

Answer:
12- 30
36- 90
Step-by-step explanation:
if she can answer 50 in 20 mins then that means she is answering 2.5 questions in 1 min and then you must multiply 2.5 by the number of mins she has making it
12 x 2.5= 30
36 x 2.5= 90
Combine (subtract) 3n and 2n to get 1n or n. Then you have n -5n =10n add 5n to 10n to get 15n. divide the 15 from n and your answer is n=15
1) a = tickets in advance goal = 2000
d =tickets at door
6a +8d = 2000
6(142)+8d =2000
852+8d=2000
8d=2000-852
8d=1148
d=1148/8
d=143.5
round up d=144 need to sell 144 tickets at door
