Answer:
1/30 chance of picking two girls
Step-by-step explanation:
Only 5 of the 25 members are girls and assuming you dont pick the first girl and put her name back in the hat. Then you would have a 1 in 30 chance of getting two girls for president and vice president.
5 min = 6.95
10 min = 11.90
18 min = x
so, the difference between 5 min and 10 min = 11.90-6.95 = 4.95
15 min = 11.90+4.95 = 16.85
now, 4.95/5 =0 .99.
Then, 16 min = 16.85+0.99 = $17.84
17 min = 17.84+0.99 = $18.83
18 min = 18.83+0.99 = $19.82 Answer
If I understood given text quite well than equation will be
4x + 3 (x+4) = -9 => 4x+3x+12=-9 => 7x=-21 => x=-21/7=-3 => x= -3
Good luck!!!
