Answer:
y=19
Step-by-step explanation:
3(y - 9) = 30
3y - 27 = 30
3y = 30 + 27
3y = 57
y = 19

Answer:
768
Step-by-step explanation:
First multiply by two
Then multiply by four
Remark
The trick here is to realize that you have to find the number both have in order to find the difference. That means you take (effectively) 3/8 and 5/8 to find out how much each of them has. The 8 stands for the 136
Step One
Find the number of stamps Alex has. Remember his ratio is the smaller so he will have 3/8
Alex = 3/8 * 136
Alex = 408/8 = 51
Step 2
Find the number that Freddy has.
The total is 136
<u>Formula</u>
Freddy = Total - Alex
Freddy = 136 - 51
Freddy = 85
<u>Check</u>
Let us see if 5/8 * 136 = 85
5*136/8 = 680 / 8 = 85 So your answers are correct.
Difference
Difference = 85 - 51 = 34 which is how many more stamps Freddy has than Alex.
So, we already know that one hive has a weight of 11.607kg and .204kg is add each week, so we add on .204kg times, w, representing weeks onto 11.607kg and our t is our total of weight of a hive with respect to weeks
So in this case our w is 7.5 weeks and now we evaluate t
Solve
Answer:
Hive's weight will increase by 1.53kg in 7.5 weeks to 13.137kg
Remark
Average in this case does not mean you take (s1 + s2)/2. What average speed means is Total Distance / Total Time.
Formula
Average speed(s) = Total Distance / Total Time
Givens
Total Distance = 252 + 30 = 282 miles
Total Time = 5 hours.
Substitute and Solve
Average speed = 282 / 5
Average speed = 56.4 miles / hour <<<<< Answer.
The other facts are not used.
