This is eassy, I'll show you
From 81%, we get fraction 81/100
After reduced 81 fraction 100, we get...
0,81 [Change into decimal]
X=39 you take 39 and 102 and add them which is 141 then subtract that from 180
<u>Answer:</u> The value of x will be 2.
<u>Step-by-step explanation:</u>
To calculate the value of 'x' or solve for x, we need to isolate x from 8.
In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.
Reverse operation of addition is subtraction.
We need to subtract 8 from both sides of the equation, we get:

By doing this, we get the value of 'x' as 2.
Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.
Answer:
5 x 4 + 2 - 3 / 1

Took me a lot of tries but got it! :) Hope this helps
The answer would be ≈1948.73 in. The formula to solve would be:
A = 6 a h + 3 √3 a²
I hope this helps love! :)
