Bacteria of species a and species b are kept in a single environment, where they are fed two nutrients. Each day the environment is supplied 19900 units of the first nutrient and 32190 units of the second nutrient. Each bacterium of species a requires 4 units of the first nutrient and 5 units of the second nutrient, and each bacterium of species b requires 1 unit if the first umnutrient and 6 units of the second nutrient. What populations of each species can coexist in the environment so that all the nutrients are consumed each day?

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

Cherie measures and records the lengths and sizes of the same style of a sandal found at a shoe store. which equation can be used to determine the approximate shoe size, s, for a foot length of x inches? s = x – 2 s = 2x – 10 s = x + 6 s = 2x + 4

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
