11, 13 and 15

note that consecutive odd integers have a difference of 2 between them

example : 1, 3 , 5

let the 3 consecutive integers be n , n+ 2, n + 4

The sum of the 3 integers divided by 3 gives the average, thus

\frac{n + n + 2 + n + 4}{3} = 13

\frac{3n + 6}{3}= 13 (multiply both sides by 3 to eliminate fraction )

3n + 6 = 3 × 13 = 39 ( subtract 6 from both sides )

3n = 39 - 6 = 33 ( divide both sides by 3 )

n = \frac{33}{3} = 11

the integers are 11, 11 + 2, 11 + 4 = 11, 13, 15

The factors of 5y^2-2y-7 are (5y-7) and ???
gladu [14]
If we expand bx to jx and kx we have:

5y^2-2y-7

5y^2-7y+5y-7  then factor...

y(5y-7)+1(5y-7)

(y+1)(5y-7)

So the other factor is:

(y+1)

Simplify £2.50 : 60p
slavikrds [6]

Answer:

Here we will simplify 2/50 to its simplest form and convert it to a mixed number if necessary.

In the fraction 2/50, 2 is the numerator and 50 is the denominator.

When you ask "What is 2/50 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.

We do this by first finding the greatest common factor of 2 and 50, which is 2.

Then, we divide both 2 and 50 by the greatest common factor to get the following simplified fraction:

1/25

Therefore, this equation is true:

2/50 = 1/25

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

1/25 = Proper Fraction

An art museum opens at 9 a.M. And closes at 5 p.M. The function V gives the number of visitors in a museum h hours after it open
liubo4ka [24]

Answer:

What the equation is telling us is that after opening for 1 hour 15 minutes, there were 28 visitors

Step-by-step explanation:

The function we are given is ;

V(1.25) = 28

what this mean is that the number of visitors in the museum after 1.25 hours of opening is 28

1.25 hours is same as 1 hour (0.25 * 60) minutes

What is in the bracket is trying to convert the 0.25 hours to minutes

Since 1 hour is 60 minutes, 0.25 will be (0.25 * 70)

Which is 1 hour 15 minutes

So after opening for 1 hour 15 minutes, the museum had 28 visitors

1/2x+40=50 What is the answer for this problem??
Mama L [17]

Answer:

x = 20.

Step-by-step explanation:

1/2x + 40 = 50

1/2x + 40 - 40 = 50 - 40

1/2x = 10

1/2x * 2 = 10 * 2

x = 20
