36 for 4 hats = 36/4 = 9 per hat
56 for 7 hats = 56/7 = 8 per hat
not equivalent

12 posters for 36 students = 12/36 = 1/3 poster per student
21 posters for 63 students = 21/63 = 1/3 poster per student
these are equivalent...although it does not make much sense...each person getting 1/3 of a poster. And if there was a mistake and it was supposed to be 36 posters for 12 students and 63 posters for 21 students...it would still be equivalent

If f(x)=1/x+2 what is f(3+h)?
Wittaler [7]
I don't know if you want the whole x+2 on the bottom or not, but I will put it on the bottom for now.
Replace x with (3+h)

f(3+h)=1/[(3+h)+2]

Now if it's supposed to be JUST x in the denominator...
Replace x with (3+h)

f(3+h)=1/(3+h)+2


Best wishes!

The sum of two consecutive ODD integers is -76. Find the integers.​
alexandr1967 [171]

Answer:

First number: -39

Second number: -37

Step-by-step explanation:

An odd number can be written as 2n+1 where n is a whole number.

Let's call our first number 2n+1.

Our second, consecutive number will be 2 more than our first number, since it has to be odd. All numbers go: odd -> even -> odd -> even. If we have an odd number, and add 2, we'll get the next odd number.

First number: 2n+1

Second number: 2n+1+2 = 2n+3

The sum of these two numbers, 2n+1 and 2n+3 will be -76.

(2n+1) + (2n+3) = -76

2n + 2n + 1 + 3 = -76

4n + 4 = -76

4n = -80

n = -20

Since our first number is 2n+1:

2 * (-20) + 1 = -40 + 1 = -39

First number: -39

Our second number is 2n+3, or 2 more than our first number.

-39 + 2 = -37

Second number: -37

We can double check this:

-39 + (-37) = -39 - 37 = -76
