Answer:
31/8*14/5=10*17/20
Step-by-step explanation:
It is m + 9 because if we let m = 60 and the lest was 9 minutes longer than m, the test would be 69 minutes long. Therefore the answer is m + 9
Answer:
D No, the integer with the larger absolute value always determines the sign of the sum.
Step-by-step explanation:
Suppose the integer you start with is +3. Adding -1 or -2 or -3 to that will result in 2, 1, or 0, none of which are negative. Only when you add a negative number with an absolute value greater than 3 will you get a sum that is negative. That is, <em>the number in the sum that has the largest absolute value determines the sign of the result</em>. (This is most important when the signs differ, but it is also true when the signs are the same.)
