Answer:
3/10
Step-by-step explanation:
- add 7+4+6+3=20
- the take how many times both coins landed on heads which is 6 and put the 6 over 20
- then divide by 2 because 2 can go into both 6 and 20
- and you end up with 3/10 which you can't simplify any more.
[8x-2y]+[3x-4y]
=8x+3x-2y-4y
=11x-6y
Answer:
248*a=391
Step-by-step explanation:
If you let X = the distance in miles from Dales's house, and understand rate = distance/ time, the rate going to mountains = x/7, and back from mountains is x/5. If dale was 18mph fast going home, the equation would be...
(coming home rate) = (going to mountain rate) + 18 which is
x/5 = x/7 + 18. Then solve for X.
Use the least common denominator = 35 so multiply everything by 35 and you get...
7x = 5x+630
simplify...
2x = 630, then
x = 315 .
Dale live 315 miles away from the mountains.
