Benjamin solved the equation 3 + x over 2 = 10 and justified each step as shown.

1 answer:

7 0

The method of solving this equation looks fine to me and the answer is correct since 3 + x/2=10 is x/2=10-3 and so x/2 =7 and so x = 14 as shown and checking, then subsituting 14 for x then x/2=7 = 10-3 so therefore it is fine the way it is.

Se corta una manzana en 12 partes, se comen ocho partes. Qué fracción simplificada a su mínima expresión representa la cantidad

lakkis [162]

Answer:

A. 1/3

Step-by-step explanation:

Dado que:

una manzana se corta en 12 partes y se comen ocho partes.

La fracción de manzanas consumidas = 8/12

= 2/3

La fracción de manzanas que quedan = valor original de la manzana que se corta - la fracción de la manzana que se come

La fracción de manzanas que quedan $=1- \dfrac{8}{12}$

La fracción de manzanas que quedan $=\dfrac{12-8}{12}$

La fracción de manzanas que quedan $=\dfrac{4}{12}$

A la fracción más baja; obtenemos = 1/3

If f(x) = 3x - 12, what is f(2)? -6 -18 18 6

dusya [7]

Answer: -6

Explanation: In this problem, we're given the function f(x) = 3x - 12 and we're asked to find f(2).

To find f(2) or the value of the function when x equals 0, we simply substitute 2 in for x in our function. So we have f(x) = 3(2) - 12 or 6 - 12 which equals -6.

So f(2) or the value of the function when x equals 2 is -6.
