Answer:

1/25

Step-by-step explanation:

At the start there is a 4/20 (1/5) chance of drawing a blue marble. After putting the marble back in the bag, there is again a 1/5 chance of drawing a blue marble again. To calculate the overall probability, you must multiply the two numbers together: 1/5 x 1/5 = 1/25.

Does anyone know know to do this ?

He drinks 8 glasses of water in one day. to know the number of glasses he drinks in 365 days, simply use cross multiplication as follows:
number of glasses per year = (365*8)/1 = 2920 glasses
so, yes his assumption is reasonable if he kept the same rate (8 glasses per day each day)

Answer:

5x + 2x.....combine like terms..... = 7x

5x + 2x....subbing in 1                               7x - 1....subbing in 1

5(1) + 2(1) = 5 + 2 = 7                               7(1) - 1 = 7 - 1 = 6

5x + 2x...subbing in 2                                 7x - 1...subbing in 2

5(2) + 2(2) = 10 + 4 = 14                            7(2) - 1 = 14 - 1 = 13

5x + 2x...subbing in 3                                 7x - 1...subbing in 3

5(3) + 2(3) = 15 + 6 = 21                            7(3) - 1 = 21 - 1 = 20

5x + 2x...subbing in 4                                 7x - 1....subbing in 4

5(4) + 2(4) = 20 + 8 = 28                            7(4) - 1 = 28 - 1 = 27

5x + 2x...subbing in 5                                 7x - 1...subbing in 5

5(5) + 2(5) = 25 + 10 = 35                          7(5) - 1 = 35 - 1 = 34

5x + 2x result values are 1 more then 7x - 1 result values

there are no values that will make the 2 expressions equal....

because 5x + 2x = 7x......and the other one is 7x - 1......so the 7x - 1 values will always be 1 number less...because ur subtracting one
