Well I think it can help even better because since you already solved and proved your work you know what to do for your answer.
I think
-85/12 _
or in decimal form its 7.08333333
or mixed number form 7 1/12
<span>80 USD = (1.0343 x 80) AUD = 82.74 AUD</span>
Answer:
14
Step-by-step explanation:
The perimeter is the sum of the sides, so we have
2x+x+15+4x-7=57
= 7x+8
Subtracting 8 from both sides, we get
7x= 49
Dividing 7 from both sides, we get
x=7
Our sides are then 2x=14, x+15=22, and 4x-7=21. 14 is our answer
it just keeps going . You keep adding the zero and subtracting.
