You are having a garage sale. at lowe's, a cash box cost $10 and for sale signs cost $7 each. you spent a total of $38 before taxes. how many for sale signs did you buy in addition to the cash box?

  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.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
