To solve this problem, we need to simplify to get x.
x ÷ 2 + 8 = 23
x ÷ 2 = 15
x = 30
Hope this helps!
<h2><em>x and x+1 are the integers
</em></h2><h2><em>x(x+1)=29+x+(x+1)
</em></h2><h2><em>x^2+x=29+2x+1
</em></h2><h2><em>x^2+x=30+2x
</em></h2><h2><em>x^2+x-2x-30=0
</em></h2><h2><em>x^2-x-30=0
</em></h2><h2><em>factor
</em></h2><h2><em>(x-6)(x+5)=0
</em></h2><h2><em>x-6=0
</em></h2><h2><em>x=6 and x+1=7
</em></h2><h2><em>6*7=29+6+7
</em></h2><h2><em>42=29+13
</em></h2><h2><em>42=42</em></h2>
You need to find 20% of $1580.00.
20% of $1580.00 =
= 20% * $1580.00
= 0.20 * $1580.00
