You find the hundredth and go to the thousandth and if it’s more than four round up if it’s less it’s rounded since it’s a 2 you round down making it 2.93
Answer:
2-4.5×3+8=-3.8
-3.8÷7=-0.5
Step-by-step explanation:
Answer:
14000:21000
Step-by-step explanation:
2:3 = 2x + 3x
2x + 3x = 35,000
5x = 35,000
x = 35,000/5
x = 7000
2x = 7000 * 2
= 14000
3x = 7000 * 3
= 21000
Answer: they are not correct
Step-by-step explanation:
To determine if they are correct, we would have to solve the equation from the previous question. Recall;
c represent the cost of a cheeseburger.
f represent the cost of medium fries.
The Browns bought 4 cheeseburgers and 3 medium fries for $16.53. It means that
4c + 3f = 16.53- - - - - - - -1
The Greens bought 5
cheeseburgers and 4 medium fries for $21.11. It means that
5c + 4f = 21.11- - - - - - - -2
Multiplying equation 1 by 5 and equation 2 by 4, it becomes
20c + 15f = 82.65
20c + 16f = 84.44
Subtracting, it becomes
- f = - 1.79
The negative sign cancels out
f = 1.79
Substituting f = 1.79 into equation 1, it becomes
4c + 3 × 1.79 = 16.53
4c + 5.37 = 16.53
4c = 16.53 - 5.37
4c = 11.16
c = 11.16/4
c = $2.79
Each cheeseburger costs $2.79 and each fry costs $1.79
Therefore, they are not correct
Answer:
7 15/16
Step-by-step explanation:
find the same denominator which is 16
3/4x4/4 = 12/16
7 3/16+12/16= 7 15/16
probably bad explanation but hope it helps.. :)
