Answer:
Division property get you to the quick solution
Solution: 3.4
Step-by-step explanation:
5*(x - 2) = 7
Dividing both sides by 5
5*(x -2)÷5 = 7÷5
x - 2 = 1.4
Adding 2 on both sides, we
x -2 + 2 = 1.4 + 2
x = 3.4

Answer:

Step-by-step explanation:
Sarah has $55
Her expenses are 3 shirts priced at $m each.
Total cost of 3 shirts at $m each would be the multiplication of each:
3 * m = 3m
The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:
Remaining Money = 55 - 3m
Sqrt(49)*sqrt (-1) -4 = 7i-4
