Answer:
The number of 57-cent stamps that Julie bought is 12
Step-by-step explanation:
Given equation
0.57 s + 0.3 ( s − 6 ) = 8.64
Open bracket
0.57s + 0.3s - 1.8 = 8.64
Collect like terms
0.87s = 8.64 + 1.8
0.87s = 10.44
Divide both sides by 0.87
s = 12

Answer:
m = 4
Step-by-step explanation:
-16 = -6m + 2m
Add -6m and 2m.
-16 = -4m
Divide both sides by -4.
4 = m, or m = 4.
Proof:
-16 = -6m + 2m
Substitute variable.
-16 = -6(4) + 2(4)
Multiply -6 and 4.
-16 = -24 + 2(4)
Multiply 2 and 4.
-16 = -24 + 8
Add -24 and 8.
-16 = -16.
