Answer:
The resistance is 7.5 ohms
Step-by-step explanation:
V = IR
V = voltage I is the current and R = resistance
120 = 16*R
Divide by 16 on both sides
120/16 = 16R/16
7.5 = R
The resistance is 7.5 ohms
Answer:59
Step-by-step explanation:
negative minus negative = positive
For the first part:Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:

With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:

So, her total is:

If you subtract 3 from the total, then the expression is:
For the second part:If she's paying 3 less for each shirt, then the cost of 3 shirts will become:

In the same fashion, for the two jeans:

So the expression for the total cost is:
For number three:The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.
For number four:If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).
So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.
