Answer:
Let no be x
algebraic expression =x-5
Step-by-step explanation:
Answer:
so make an equation. You now that RS=6n and RS=42. ST is the total sum of all points so the equation would be 6(42)=35. 6X42= 252. Divide 252 by 35 and your answer should be A: 7
Step-by-step explanation:
Answer:
the correct answer is j=12+7
Answer:
23/24
Step-by-step explanation:
To find the sum you must ad.
Fractions can only be added and subtracted when the denominators (the bottom numbers) are the same.
24 is the smallest number that 2, 3 and 8 go into.
1/2 = 12/24, 1/3 = 8/24, 1/8 = 3/24

23/24
Recall your d = rt, distance = rate * time
now, if say, by the time they meet, Mr Cunningham has travelled "d" miles, that means Mrs Cunningham must also had travelled "d" miles as well.
However, he left 3 hours earlier, so by the time he travelled "d" miles, and took say "t" hours, for her it took 3 hour less, because she started driving 3 hours later, so, she's been on the road 3 hours less than Mr Cunningham, so by the time they meet, Mrs Cunningham has travelled then "t - 3" hours.
