Answer:

$\frac{7}{9}$

Step-by-step explanation:

If you add a number that is negative, you are basically subtracting it.

This means that

$\frac{8}{9}+\left(-\frac{1}{9}\right)=\frac{8}{9}-\frac{1}{9}$

Since they both have the same denominator, you can easily subtract the fractions: $\frac{8-1}{9}=\frac{7}{9}$

Write a word problem for the equation. 1/2 (x-4) = 1/3x + 2

Ganezh [65]

Answer:

Half the age of Carlos four years ago is 2 years more than one-third his current age.

Step-by-step explanation:

We want to write a word problem for the equation.

$\frac{1}{2} (x - 4) = \frac{1}{3}x + 2$

Let x represent the present age of Carlos.

Four years ago, Carlos was x-4 years.

Half his age four years ago is ½(x-4)

Two years more than one-third his current age is ⅓x+2
