- If you divide a number by four and then add six, you get eighteen. What is the number?

stiks02 [169]

Answer:

Step-by-step explanation:

Create an equation to represent this, where x is the unknown number.

$\frac{x}{4}$ + 6 = 18

Solve for x, by first subtracting 6 from both sides:

$\frac{x}{4}$ = 12

Multiply each side by 4:

x = 48

So, the number is 48

Solve the inequality.

marysya [2.9K]

Answer:

$\huge x > \frac{7}{3} \\$

Step-by-step explanation:

$8( \frac{1}{2} x - \frac{1}{4} ) > 12 - 2x \\$

Expand the terms in the bracket

That's

$8( \frac{1}{2} x) - 8( \frac{1}{4} ) > 12 - 2x \\ 4x - 2 > 12 - 2x$

Move -2x to the other side of the inequality

$4x + 2x - 2 > 12 \\ 6x - 2 > 12$

Move - 2 to the other side of the inequality

$6x > 12 + 2 \\ 6x > 14$

Divide both sides by 6

$\frac{6x}{6} > \frac{14}{6} \\$

We have the final answer as

$x > \frac{7}{3} \\$

Hope this helps you
