You can rewrite the decimal as a fraction  and compare the two fractions.  The fractions need to have a common denominator.

You can change the fraction to a decimal and compare.  take the numerator and divide it by the denominator.  


Unless I recognize the decimal as a fraction right away, I find it much easier to write the fraction as a decimal and compare

Find the possible value or values of y in the quadratic equation z^2 - 4z+ 4 =0
jeyben [28]
Didn't you mean "Find the possible value or values of z?  y is not at all present in this equation.

z^2 - 4z + 4 = 0 can be factored into (z-2)(z-2).  Thus, the given equation has two equal, real solutions:  z=2 and z=-2.

^Solve for x. Please help me if you can I really need the answer
vagabundo [1.1K]

Answer:

x ≈ 25.1

Step-by-step explanation:

Using the sine ratio in the right triangle

sin26° = \frac{opposite}{hypotenuse} = \frac{11}{x} ( multiply both sides by x )

x × sin26° = 11 ( divide both sides by sin26° )

x = \frac{11}{sin26} ≈ 25.1 ( to 1 dec. place )
