Q:

1. Which expression is equivalent to −2.1+(−5.9)+(−3.7) ?−2.1−(5.9+3.7)−(2.1−5.9)+(−3.7)(2.1+5.9+3.7)(2.1+5.9)+(−3.7)2. Which expression is equivalent to −40+(−20)+(−60) ?−(40−20)+(−60)−20+(−40)+(−60)−40−(20−60)40+20+603. Select from the drop-down menu to correctly identify the property shown.(associative, commutative, distributive)−1.4+(−2.6+3.8)=(−1.4+(−2.6))+3.84. Select from the drop-down menu to correctly identify the property shown.(associative, commutative, distributive)−7.9+(−9.03+(−0.1))=−7.9+(−0.1+(−9.03))5. Use properties of addition to evaluate the expression.−35+7+(−15)Enter your answer in the box.
