Answer:

  4 signs

Step-by-step explanation:

The total amount you spent is ...

  cash box cost + sign cost = total amount

You are told the cash box costs $10, the signs are $7 each, and the total is $38. If n is the number of signs, then the total amount is ...

  $10 + $7 × n = $38

Subtracting the cost of the cash box gives the amount you spent on signs:

  7n = 28

Dividing by 7 gives the number of signs:

  28/7 = n = 4

You bought 4 signs.

What is the solution to the inequality - 6x + 5 &gt; -1
ExtremeBDS [4]

[ Answer ]

\boxed{X \ < \ 1}

[ Explanation ]

  • Solution To Inequality: - 6x + 5 > -1

-------------------------------------

  • Subtract 5 From Both Sides

- 6x + 5 - 5 > -1 - 5

  • Simplify

-6x > -6

  • Multiply Both Sides By -1 (Reverse Inequality)

(-6x)(-1) < (-6)(-1)

  • Simplify

6x < 6

  • Divide Both Sides By 6

\frac{6x}{6} < \frac{6}{6}

  • Simplify

X < 1

\boxed{[ \ Eclipsed \ ]}
