**Answer:**

yes

they are equivalent because lets say the X = 3 then you would have to answer

3 + 3 + 1 + 3 + 2 + 3 + 1 + 3

and that would = 19

and then on the other equation

5 x 3 + 4 = 19

**So the both equal the same.**

**Step-by-step explanation:**

**Answer:**

d) 54

**Step-by-step explanation:**

Let's name x the age of Kylie.

Then we have:

**K = x**

Joan is 2 years younger than Kylie ⇒ **J = x - 2**

Kylie is 3 years older than Lilian ⇒ **L = x - 3**

Miriam is one year older than Joan ⇒**M = (x - 2) + 1 = x - 1**

If we sum up all ages we get: **x + x -2 + x - 3 + x - 1 = 4x - 6**

<u>Therefore, the sum of all ages is 4x - 6. </u>

Let's make **x = 14** ⇒ 4x - 6 = 4(14) - 6 = **50**

Let's make **x = 15** ⇒4x - 6 = 4(15) - 6 =** 54**

Let's make **x = 16** ⇒4x - 6 = 4(16) - 6 = **58**

If we substitute for smaller x, we'll get values smaller than 50 and if we substitute for x >16 we'll get values greater than 58.

Looking at the options given by the problem, we can see that the only one that fits into the equation is d) 54.
