sal recorded the outdoor temperature as -4°F at 7:30 am . at noon , it was 22°F . sal said the temperature changed by 18°F because 22-4=18. Is sal right or wrong .

Step-by-step explanation:

Temperature change:

Sal is wrong as the difference should be calculated as subtraction of the two values and absolute value of the result should be taken as the answer

Sal was wrong as the change of temperature is 26°F

Step-by-step explanation:

recorded temperature at 7:30 A.M. = -4°F

                                             at noon = 22°F

change of temperature = 22 - (-4) = 26°F

therefore, Sal was wrong as the change of temperature is 26°F

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
