Question

minus 7 by 16 + 13 by minus 15 + 27 by 20​

Answer 1

Answer:

Step-by-step explanation:

Recognizing the structure of this inequality provides one solution strategy. With this strategy, a student will look at the relationship between minus 3 t plus 1 and 9 t minus 3 and recognize that the latter is −3 multiplied by the former.

Multiplying all parts of the inequality by −3 reverses the inequality signs, resulting in 27 over 5 greater than 9 t minus 3 greater than 21 over 4 comma or rather 21 over 4 less than 9 t minus 3 less than 27 over 5 when written with increasing values from left to right. Any value greater than 21 over 4 and less than 27 over 5 is correct.
