Answer:

Step-by-step explanation:

Diagonals of a rhombus are perpendicular bisector.

Hence, triangle ABE so formed would be a right triangle right angled at E.

Therefore, by Pythagoras theorem:

$AB = \sqrt{AE^2 + BE^2 } \\ \\ \therefore \: AB = \sqrt{5^2 + 12^2 } \\ \\ = \sqrt{25 + 144} \\ \\ = \sqrt{169} \\ \huge \red { \boxed{ \therefore \: AB= 13}}$

cuanto pagaríamos por un libro cuyo precio es de $25 si le aplicamos un descuento del 25% cuanto dinero ahorramos

kotegsom [21]

Tenemos precio de lista de $25 para el libro.

Si aplicamos un descuento del 25%, este descuento representa:

$D=(\frac{25}{100})\cdot25=0.25\cdot25=6.25$

Ahorramos $6.25.

El precio que pagamos el libro es $18.75.

$P=L-D=25-6.25=18.75$

8 wholes and 4/6 minus 2 wholes and 5/6 is what

podryga [215]

The answer to your problem should be 5 wholes and 5/6 since the denominators are the same just add 6 more pieces to 4/6 to get an improper fraction then subtract to get the answer. Hope this helps and have a fabulous day!

Solve for y. 6x-4y=-16

musickatia [10]

$y = \frac{6}{4} x + 4$

Explanation:
1. you subtract 6x to get 4y alone. which will get you -4y=-6x-16
2. then you divide everything by -4 to get y completely alone.
This will get you the answer of y=6/4y+4
