There are a total of 7C2 of options for Ryan's mom to choose.

If Ryan's mom picks Saturday and Sunday, this is the only 1 option in those 7C2 of options. Thus, the propability is (1 / 7C2) × 100% = 4.762%.

Answer:

Probability that she picks Saturday and Sunday = 1/21 = 0.0476

Step-by-step explanation:

Total number of days in a week = 7

Number of days selected = 2

Total number of combinations = 7C₂ =\frac{7*6}{1*2} =21

Total number of favorable ways = 1 that is  Sunday and  Saturday.

Probability that she picks Saturday and Sunday = 1/21 = 0.0476

faltersainse [42]

Answer:

6(4x-1) is equivalent to 24x-6 and (2*12x)-(2*3)

24x+6 is equivalent to 6(4x+1) and (6*4x)+(6*1)

(4*6x)+(4*2) is equivalent to 24x+8 and 4(6x+2)

Step-by-step explanation:

An equivalent expression is an expression which either simplified or factored is equal to it.

6(4x-1) is equivalent to 24x-6 and (2*12x)-(2*3)

24x+6 is equivalent to 6(4x+1) and (6*4x)+(6*1)

(4*6x)+(4*2) is equivalent to 24x+8 and 4(6x+2)
