A math club has 100 members. The number of girls is 5 less than 2 times the number of boys how many members are boys how many members are girls
Answers
Answer 1
Answer:
let the number of boys be x according to question, the number of girls is (2x-5) therefor, x+(2x-5)=100 x+2x-5=100 3x=100+5 x=105/3 x=35 hence the number of boys is x =35 and the number of girls is 2x-5=2*35-5 =70-5 =65.
Answer 2
Answer:
g = girls. b=boys 100=g+b g= 2b-5 we can plug this in to the first equation to find out the number of boys. 100= 2b-5+b put your B's together 100= 3b-5 And solve it out. 100=3b-5 +5. +5 105 =3b divide 105 by three 35=b You now have how many boys are in the club. Plug this number in and solve for g 100=g+35 -35. -35 65=g There are 65 girls and 35 boys
Jordan drove for 6 hours at 55 miles per hour, while Matt drove for 3 hours at 60 miles per hour. If Isaac drove 82 miles longer than Jordan and Matt drove combined, for how many miles did Isaac drive?--------- miles
(Hint: Rate × Time = Distance)
Answers
If you look at the equation, we have to multiply the hour and the mph(miles per hour) together to find how many miles they drove. For Jordan, we would have to multiply 6 times 55 which is 330. Jordan drove 330 miles. For Matt, we have to multiply 3 times 60, which gets us 180. Together, they would have drove 510 miles. If Isaac drove 82 miles longer than Jordan and Matt drove combined, we would get 582 miles. Isaac drove 592 miles.
