let x = a number

difference means that its subtraction

twice a number is 2x

so the equation should be

2x-5=3

add 5 to both sides

2x=8

divide both sides by 2

x=4

What is the value of a?
Juli2301 [7.4K]
Actually, the answer is not A, if you're saying A is the first choice above.  That's incorrect.  You will need to use the Geometric mean for right triangles here to figure out what the value of a is.  We will use this form: \frac{YZ}{WZ} = \frac{WZ}{XZ}.  We have a value for YZ of 3; side a is XZ.  That means in order to solve this we need WZ, which we can find using pythagorean's theorem.  3^2 + 4^2 = c^2 and 9 + 16 = c^2 and c = 5.  Now we fill in accordingly: \frac{3}{5}= \frac{5}{XZ}.  Cross-multiply to get 3XZ=25 and side XZ is \frac{25}{3}.  XZ is 25/3 and YZ is 3, so 25/3 - 3 = XY.  That means that XY (side a) = 16/3 or 5 1/3, choice B, or the second one down.
