1. The temperature of a substance is -29.9°F. The temperature decreases by 8.7° and then again by 17.8°. Emilia write two strategies to find the final temperature of the substance. Strategy 1: Evaluate the expression -30 - 8 - 17 - 0.1 - 1.5. Strategy 2: evaluate the expression -29 - 8 - 17 - 1 - 0.4. 2.Which TWO statements are TRUE? A. The final temperature of the substance is -56.4°. B. Evaluating -29.9 - 8.7 - 17.8 is the same as evaluating -30 - 8 - 17 - 0.1 - 1.5, so strategy 1 is correct. C. Evaluating -29.9 - 8.7 - 17.8 is the same as evaluating -29 - 8 - 17 - 1 - 0.4, so strategy 2 is correct. D. Strategy 1 would be correct if the -30 is replaced with a -29. E. Strategy 2 would be correct if the 1 is replaced with a 2.
