Question

The sum of a number times 9 and 21 is at most -25.

Answer 1

x>= -46/9 (x greater than or equal to -46/9)

Explanation:

when translating the question, at most means that it is less than or equal to the value being named, therefore the equation is 9x+21<= -25

to begin solving we subtract 21 from both sides and get 9x<=-46

then when we divide by 9 we have to flip the less than sign because we have to flip it if we multiply or divide.

This gives us the answer, x>=-46/9 which does not simplify any further
