Answer:
She started with $6.00.
Step-by-step explanation:
1. This problem is meant to have you work backwards from the information given. Firstly, it is important to write all the expenses and earnings she had to her weekly earnings.
Starting Amount = ?
- $0.45 (candy bar)
- $2.50 (pen)
+ $.200 (mom)
End Total = $5.05
2. With this information, this next step will be much easier. With this process, you can now use inverse operations to undo the last few equations.
Firstly, $2.00 given by her mom will be subtracted from $5.05.
Secondly, with our new total of $3.05, $2.50 from purchasing the pen will be added to this amount. This leaves you with $5.55.
Lastly, the $0.45 cents she spent with the candy bar will be added to the $5.55.
This leaves the starting amount to $6.00.
3. She started with $6.00
Answer:
G, 7 cm
Step-by-step explanation:
the volume of a box is V = lwh
in this problem, we know the volume, length, and width and we are asked to find the height. lets plug in the known values into the formula
378 = (6)(9)h <multiply 6 and 9 together
378 = 54h
now we want to divide both sides by 54 to get <em>h</em> alone, and we will have our answer for the height
378/ 54 = 7
54h/54 = h
h = 7
our height for this box is 7 cm, we can plug this into the original equation to check, but it is not necessary
