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
Answer:
the range is 1.6 to 6.1
Step by Step:
2 sides of a triangle have to be greater than the third
add 3.7 and 5.2 this gives you 8.9, which means 8.8 is the greatest number that side can be
1.6 is the lowest the side could be because if it was anything lower then 5.2 would be greater than the sum of 3.7 and this side were calculating
that gives you the range 1.6 to 8.8 now we play a little bit of guess a d check trying to make the range fit the last piece of information that we were given that the perimeter is between 10 and 15
the perimeter is the sum of all the sides so pick different numbers from the range we found and play guess and check to find which ones are too high or low in this case the numbers were only to high
the highest number you can have that is within the range we found but fits the perimeter is 6.1
therefore the range 1.6 to 6.1
Answer:
7 
Step-by-step explanation:
45/6 = 7 Reminder 3
3/6 = 1/2
Therefore, the answer as a mixed number in simplest form is 7
