Answer:
$2.59
Step-by-step explanation:
Let b and m represent the costs of a banana split and a milkshake, respectively. Then the two purchases are ...
b +5m = 16.24
3b +2m = 15.05
Subtracting the second equation from 3 times the first, we have ...
3(b +5m) -(3b +2m) = 3(16.24) -(15.05)
13m = 33.67 . . . . . . simplify
m = 2.59 . . . . . . . . . divide by 13
The cost of a milkshake is $2.59.
Answer:
2 >x
Step-by-step explanation:
5 - 4x > 3x - 9
Add 4x to each side
5 - 4x+4x > 3x+4x - 9
5 > 7x-9
Add 9 to each side
5+9> 7x-9+9
14>7x
Divide each side by 7
14/7 >7x/7
2 >x
