First, you have to combine like terms so -13-3z=9z-1 ; Then you have to do the variables so -13=12z-1 or -13-12z=-1 ; Next, you have to do the constant numbers so -12=12z or 12z=-12 ; Finally you divide so -12/12z = z=-1

5-3z-18=z-1+8z
Add like terms
-13-3z=9z-1
Move terms
-12z=12
Divide both sides by 12
z=1

Convert the following to scientific notation: 0.000665.
BaLLatris [955]
- - Step 1: Move the decimal point to the right, until you get greater then 1 and less than 10. In this case we moved it till we got 6.65.
- - Step 2: Count how many times you moved the decimal over: In this case, we moved it 4 times.
- - Step 3: All you have to do now is chose which one has 6.65 over -4.
 (We are saying negative because when you move it to the right, it becomes negative.)
Final answer: A

Samantha had $15.She spends $2.25 on admission to the ice skating rink, $2.15 to rent ice skates and $1.35 each for 2 hot chocol
jolli1 [7]

Answer: $7.90

Step-by-step explanation:

When we see how much she spent on the total cost of renting skates, getting in, and getting hot chocolate, we can see that she is going to subtract all of that from the total cost.

$15.00 - 2.25 = 12.75

12.75 - 2.15 = 10.60

10.60 - 1.35 = 9.25

9.25 - 1.35 = 7.90 remaining

We know that she payed 2.25 to get in, 2.15 for skate rental, and 1.35 for each hot chocolate she purchased which in this case is 2. We need to subtract all of this from 15 and get the final answer
