Sometimes, because if the number is negative, the opposite is greater, but if the number is positive, the opposite is smaller.
Answer:
19
Step-by-step explanation:
19 x 2 = 38
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
Queremos encontrar la medida de un lado de un rectangulo, dado que conocemos la longitud del otro lado y el area del rectangulo.
Veremos que el otro lado del rectangulo mide 3/5 cm
Sabemos que para un rectangulo de largo L y ancho W, el area esta dada por:
A = L*W
En este caso sabemos que el area es igual a (15/40) cm^2.
Y sabemos que uno de sus lados (digamos que es el ancho) mide (5/8) cm.
Entonces podemos reemplazar eso en la ecuación del area:
(15/40) cm^2 = L*(5/8) cm.
Ahora podemos resolver esto para L.
L = (15/40 cm^2)/(5/8 cm) = (15/40 cm^2)*(8/5 cm^-1)
L = 3/5 cm
El otro lado del rectangulo mide 3/5 cm
