Tre determines the solution to the equation 3.57x + 1.61 = 2.63x is x = 0.5. He verifies his solution using the steps below. Step 1. 3.57(0.5) + 1.61 = 4.71 - 2.63(0.5)
Step 2. 1.785 + 1.61 = 4.71 - 1.315
Step 3. 3.395 = 6.025
Which statement most accurately describes Tre's Error
A. Tre made an error when determining the original solution of x = 0.5
B. Tre made an error when substituting the solution in for x.
C. Tre made an error when multiplying each coefficient by 0.5
D. Tre made an error when adding or subtracting.

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.

‼️‼️‼️‼️‼️the pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is 440 f, find the pressure exerted when the temperature of the gas is 380°f. (show work)
