a meteorologist announces that yesterday's high temperature was within 4 degrees celsius of 18 degrees celsius all across the country. write an inequality that involves an absolute value to represent yesterday's high temperature. solve the inequality and explain the meaning of the solution.
lx-18l is less than or equal to 4
x-18< =4 x-18< =-4
x-18+18< =4+18 x-18+18< =-4+18
x< =22 or x< =14
14< =x< =22
is this correct?
