The answer is p>0 because the variable can not be negative so we multiply by negative 1 to get a positive and then the sign switches sides if you need further explanation download PhotoMath
Answer:
The Distributive Property combines multiplication and addition.
Step-by-step explanation:
Answer: $350+$85w greater than or equal to $715
Explanation:
$350 = already saved up money
$85w = additional money each week (we don’t know how many weeks we need to save up in order to reach our goal, so the number of weeks is unknown)
The sign is greater than or less than because you either have to reach the exact total of $715 or more than that.
Now, solve.
$350+$85w greater than or equal to $715
$85w greater than or less than $365
w greater than or less than 4

Thus, the final answers are 1 and -1/8.
The sales taxes are $3 : $37,5 x 8/100
The total is 47,79 $ because you do 37,5x8/100+37,5 and this is 40,5$ and after you do 40,5$x18/100+40,5$ and taht makes 47,79$
