Ranger's friend, Foster, wanted to challenge him by creating this expression involving two sets of parentheses with fractions:1 3 (9x − 15) 4(x 1 2 ) Ranger showed his first two steps below. 1. Distribute 1 3 and 4 through the parentheses: 1 3 (9x) − 1 3 (15) 4(x) 4(1 2 ) 2. Find each product: 3x − 5 4x 2 3. Combine like terms: What should Ranger write for step 3?

This graph represents four ecosystems. each ecosystem has a different number of species, adding to its biodiversity. different colors represent different species. which statements correctly summarize the data depicted by the graph? 1. ecosystem d has more biodiversity than ecosystem c. 2. ecosystem b has more biodiversity than all the other ecosystems. 3. ecosystem a has more biodiversity than ecosystem b but less biodiversity than ecosystem c. 4. ecosystem b has more biodiversity than ecosystems c and d but less biodiversity than ecosystem a. 5. ecosystem a has more biodiversity than ecosystem c but less biodiversity than ecosystem b.
