Answer:

The exact solution is (5 ± √17) / 4.

Step-by-step explanation:

2x^2 = 5x-1

2x^2 - 5x + 1 = 0

then,

a = 2, b = -5, c = 1

Now, by using quadratic formula,

(-b±√(b²-4ac)) / (2a)

(5 ± √(-5)^2 - 4(2)(1)) / 2×(2)

(5 ± √17) / 4.

The number of stamps that kaye and alberto had were in the ratio 5 : 3, respectively. after kaye gave alberto 10 of her stamps,
Gala2k [10]
K:A
5:3 (before)
15:9

since the total number of stamps didn't change, the total ratio should be the same.

7:5(after)
14:10

so this means 1 unit is 10stamps.

14-10=4
4 X 10= 40

Kaye have 40 more stamps than Alberto.

barxatty [35]
He weighs 196 lbs and 6 ounces. if you add the pounds (180 to 3, 5, 6)you get 194. then you add he ounces, and remember that there are 16 ounces in a pound and 8 ounces in a cup, (6 to 9, 12, 11) you get 2lbs and 6 ounces. then you add the 2 extra pounds to the 194 and you get, all together, 196 lbs and 6 ounces.

295 x 3 = 885

The distributive property is when you distriute numbers if they are getting multiplied by the same number.

Original Equation: A(B+C)

Distribute the equation so that B and C are by itself.

New Equation: AxB + AxC

This is distributive property.
