A college writing seminar increased its size by 50\PP, percent from the first to the second day. If the total number of students
Jobisdone [24]

Answer: There were 10 students in the class on the first day.

Step-by-step explanation:

Let x be the number of students of the first day.

Given: A college writing seminar increased its size by 50 percent from the first to the second day.

i.e. Number of students on second day = (Number of students on first day)+(50% of Number of students on first day)

= x +50% of x

= x+0.50x

= (1.50)x

=1.50x

Since, it is given that  the total number of students in the seminar on the second day was 15.

i.e. 1.50x=15

\Rightarrow\ x=\dfrac{15}{1.5}\Rightarrow\ x=\dfrac{150}{15}\\\\\Rightarrow\ x=10

Hence, there were 10 students in the class on the first day.

Three consecutive integers sum to 6. What is the least of these integers?
dexar [7]

Answer:

The least of the three integers is 1.

Step-by-step explanation:

Hi there!

Let <em>x</em> be equal to the least of these integers.

Let <em>x</em>+1 and <em>x</em>+2 be the next consecutive integers.

We're given that these integers have a sum os 6.

We can use these to construct an equation:

(x)+(x+1)+(x+2)=6

Combine like terms:

x+x+1+x+2=6\\x+x+x+1+2=6\\3x+3=6\\3x=3\\x=1

Therefore, the least of these integers is 1.

The other two integers would be 2 and 3.

I hope this helps!
