Answer:
a=8+1/2
Step-by-step explanation:
We move all terms to the left:
(a+5)2/3-(9)=0
We multiply all the terms by the denominator
(a+5)2-9*3=0
We add all the numbers together, and all the variables
(a+5)2-27=0
We multiply parentheses
2a+10-27=0
We add all the numbers together, and all the variables
2a-17=0
We move all terms containing a to the left, all other terms to the right
2a=17
a=17/2
a=8+1/2
82 kilograms divided by 0.10 = 8.2
82 kilograms + 8.2 kilograms = what the scale will really show which is 90.2
82 ÷ 0.10 = 8.2
82 + 8.2 = 90.2
You can multiply 5.4 and 100 or you can also multiply 1.17 and 100.
