<span>let n+2=u
so, the equation became= [2/u]-[3/u]=5
=> [(2+3)/u]=5
=> 5/u=5
=> u=5/5=1
thus, u=1
we know u=n+2
so, n+2=1
=> n=1-2=-1
so, n=-1</span>
Move the decimal so that there is one whole number.
0.00000482 => 4.82
We moved 6 units to the left so:
4.82 * 10^-6
Answer:
Joshua's account had a greater change.
Step-by-step explanation:

1. 21,150
2. 2.5193
3. 27.98
4. 11,100
Because it's iscosceles, angle 1 is similar size to the angle on the right leg.
∠1 = 67°
The sum of interior angles in trapezoid equals to 360°.
And because it's iscosceles, the upper angles are in the same size. We can write it as,
the sum of angles = 360°
67° + 67° + ∠2 + ∠2 = 360°
134° + 2 × ∠2 = 360°
2 × ∠2 = 360° - 134°
2 × ∠2 = 226°
∠2 = 113°
Final answer
∠1 = 67°
∠2 = 113°
