diversity in the ecosystem happens as a result of evolutionary pressure
Tundras, Rainforests, coral reefs and deciduous forests all are formed as a result of evolutionary pressures. Even seemingly small evolutionary interactions can have large impacts on the diversity of the ecosystems throughout the world.
Answer:
You can not tell unless you have information about the relationship between the small and large boxes (for example, a large box is 2 times the weight of a small box) You can only tell that a small box and a large box's weight together is 34.5 kilograms.
Step-by-step explanation:
3L + 5S = 135
9L + 7S = 279
12L + 12S = 135 + 279
12(S+L) = 414
S+L = 34.5
Jackson sold 27 pounds of bananas and 12 pounds of grapes.
Given that Jackson runs a farm stand that sells bananas and grapes, and each pound of bananas sells for $ 1 and each pound of grapes sells for $ 2.25, and Jackson sold 15 more pounds of bananas than pounds of grapes and made $ 54 altogether, to determine the number of pounds of bananas sold and the number of pounds of grapes sold the following calculation must be performed:
- 25 x 1 + 10 x 2.25 = 25 + 22.50 = 47.50
- 26 x 1 + 11 x 2.25 = 26 + 24.75 = 50.75
- 27 x 1 + 12 x 2.25 = 27 + 27 = 54
Therefore, Jackson sold 27 pounds of bananas and 12 pounds of grapes.
