X−7< 14 options: x< 7 x> 21 x< 21 x> 7

This is a simple equation:

x - 7 < 14

x < 14 + 7

x < 21

→ Many people think that because there is not "=" sign they don't flip the sign of what in this case is -7. But actually, the symbols "<" and ">" act as the equal sign. This rule doesn't apply to positive number, only negative.

x - 7 < 14

To solve, you must isolate the x. Add 7 to both sides

x - 7 (+7) < 14 (+7)

x < 14 + 7

x < 21

x<21, or (C) is your answer

Note: You only flip the signs if you are multiplying or dividing by a negative number

answer: your gay

step-by-step explanation:

you dont know math

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
