<span> 20. Let x represent the amount of books he had:
x + 6 = 1.12x
Subtract x from both sides:
6 = 0.12x
Divide both sides by 0.12; x = 50
</span>
<span>28. $6 + 0.025*$6 = $6 + $0.15 = $6.15 </span>
Answer:
x=10
Step-by-step explanation:
I think..i tired
Divide both sides by 55.
{x}^{2}=-\frac{500}{5}x2=−5500
2
Simplify \frac{500}{5}5500 to 100100.
{x}^{2}=-100x2=−100
3
Take the square root of both sides.
x=\pm \sqrt{-100}x=±√−100
4
Simplify \sqrt{-100}√−100 to \sqrt{100}\imath√100ı.
x=\pm \sqrt{100}\imathx=±√100ı
5
Since 10\times 10=10010×10=100, the square root of 100100 is 1010.
Formula to find the slope:
m = y2-y1 / x2-x1
(4,3); (8,5)
m= 5-3 / 8-4
m = 2/4
m = 1/2
Therefore, the slope of the line that passes through these points is 1/2
Answer:
z = 3.3
Step-by-step explanation:
Given
2.2 = z - 1.1 ( add 1.1 to both sides )
3.3 = z
