students in a speech contest. Yesterday,
1
4
of them gave their speeches. Today,
2
5
of the remaining students gave their speeches. How many students still haven't given their speeches?
To find the number of students who haven't given their speeches, subtract the number of students who have given their speeches from the total number of students. Yesterday, 14 students gave their speeches and today, 25 more students gave their speeches. So, there are 41 students who still haven't given their speeches.
To find the number of students who haven't given their speeches, we need to subtract the number of students who have given their speeches from the total number of students.
Yesterday, 14 students gave their speeches, so there are 80 - 14 = 66 students remaining.
Today, 25 students gave their speeches, so there are 66 - 25 = 41 students who still haven't given their speeches.

If the weight of hardcover version is double the weight of paperback version then weight of hardcover version is 2.8 pounds and the weight of paperback version is 1.4 pounds.
An equation is a relationship between variables in equal to form. It is evaluated to find the values of variables.
The weight of hardcover book is h
The weight of paperback version is p.
According to question:
h=2p (weight of hardcover version is double the weight of paperback version)
h+ p= 4.2 (weight of hardcover version and weight of paperback version is equal to 4.2 pounds)
Put the value of h=2p in h+ p=4.2
2p+p=4.2
3p=4.2
p=1.4
Put the value of p=1.4 in h=2p to get the value of h
h=2p
=2*1.4
=2.8
Hence the weight of hardcover version is 2.8 pounds and the weight of paperback version is 1.4 pounds.
