8 x 5 = 32 is the expression. Since Sergei caught 4 striped fish that all weigh the same, we know that we can multiple the weight of one fish by the amount of fish he caught.
Since he also caught another fish that would make the total of fish 5.
Answer:Perimeter of a rectangle is 2*the length plus 2*the width
P = 2L + 2W and P = 130, so
L + W = 65
Three times the length is equal to 10 times the width, giving
3L = 10W
Substituting into the above for L = 65 – W,
3(65 – W) = 10W
195 – 3W = 10W
195 = 13W
W = 195/13 = 15
W = 15 yards,
And L = (10/3)W = (10/3)*15 = 50
L = 50 yards
Step-by-step explanation:
5*8=40
Answer: the total change in time was 40 seconds
Hope this helps:)
There are several information's of immense importance already given in the question. based on those given information's the answer to the question can be easily derived.
Total number of students = 840
Then
Number of students going to the concert = (7/12) * 840
= 7 * 70
= 490 So
Number of students not going to the spring concert = 840 - 490
= 350
So 350 students did not go to the spring concert.I hope the procedure is clear enough for you to understand. You can always use this procedure for solving similar problems in future without requiring any help from outside.
