Answer:

b= 15/7

Step-by-step explanation:

multiplying a positive and a negative equals a negative (+)x(-)=(-)

2= - 1/7 x 1 + b

any expression multiplied by 1 stays he same

2= - 1/7 + b

move variable to the left hand side and change the sign

- b +2= - 1/7

move constant to the right hand side and chane the sign

- b= -1/7 -2

calculate the difference

-b = -15/7

chnage the signs on both sides of the equation

b=15/7

Hope this helpsI would really appreciate a brainliest??? <3

Monday<br> What time is 5 3/4 hours after<br> 11:32 pm?
Marina86 [1]

bearing in mind that the an hour has 15 + 15 + 15 + 15 = 60 minutes, so 15 minutes in 1/4 of an hour, thus 45 minutes is 3/4 of an hour.

now, from 11PM, if we add the 5 hours first, we'll be at 4AM, pass midnight of course.

now let's add the minutes, 32 and then 45, that gives us 77 minutes.

so the time will be 4AM plus 77 minutes, since 60 minutes is 1 hr, so 4AM plus 1 hr and 17 minutes, that'd be 5:17AM.

no. of ways to produce 7=3

(1+6=7, 2+5=7, 3+4=7)

no. of ways to produce 11=1

(5+6=11)

there are 4 ways in total. 4/36 simplify it to be 1/9

second qn im not sure but i think its

1/9 x 50 = 50/9 = 5 x (5/9)

round it off to the smaller whole no. which is 5 so i think its 5 times in 50 trials
