I do not think it is, because when you plug in 1/5 for X you do not get 13/15

(x + 3)/(4 - x) = 13/15
15(x + 3) = 13(4 - x)
15x + 45 = 52 - 13x
15x + 13x = 52 - 45
28x = 7
x = 7/28 = 1/4

Therefore, 1/5 is not a solution

The perimeter of a rectangle is 48 in. if the length is twice the width, what is the length of the rectangle?

Scilla [17]

B. 16

if the length of each side is 16in, the total length would be 32in.
(16 x 2 = 32)
because the length is equal to twice the width, divide 32 by 2
(32/2 = 16)

16 + 32 = 48

10. from the question; the circle theorem obeyed is "angled formed by semi-circle"

The angle formed in a semicircle is 90 degrees, hence

$m\angle XYZ=90^{\circ}$

This gives

$m\angle YXZ\text{ + m}\angle YZX\text{ = 90}$

But

$\begin{gathered} m\angle YXZ\text{ = 2x + 8} \\ m\angle YZX\text{ = 5X - 2} \end{gathered}$

Substituting values we get

$\begin{gathered} 2x\text{ + 8 + 5x - 2 = 90} \\ 2x\text{ + 5x + 8 - 2 = 90} \\ 7x\text{ + 6 = 90} \\ 7x\text{ = 90 -6} \\ 7x\text{ = 84} \\ \text{divide both sides by 7} \\ x\text{ = }\frac{84}{7} \\ x\text{ = 12} \end{gathered}$

hence, x =12
