oh this is easy! it just means 121 divided by 11, which is a whole number anyway. you just need to know your 11 times tables.
11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121,...
the answer is 11 because 11 goes into 121, 11 times.
Answer:
c
Step-by-step explanation:
17,500 cause when you dived 105,000 by 12 you get 8750 then that × 2 is 17,000
Answer:
Each hot dog is worth 5.7
Each bun is worth 2.4
Step-by-step explanation:
3d + 2b = 21.9
2d + 5b = 23.4
multiply the first by 2 and the second by 3
6d + 4b = 43.8
6d + 15b = 70.2
the coefficeint of d is the same in both equations, so subtract the first from the second
11b = 26.4
divide
b = 2.4
each bun is worth 2.4
take the first equation and plug the price of buns in
3d + 2b = 21.9
3d + 2(2.4) = 21.9
3d + 4.8 = 21.9
3d = 17.1
d = 5.7
each hot dog is worth 5.7
A method you could use to do this more easily or check your answers would be to graph the fuctions used on a website like desmos
