Marcky has three tables of different
lengths in his house. One has a length
of 4 1/2 feet, another has a length
of 4 feet, and a third has
length
of 2 1/2 feet. What is the length of
all three tables when pushed end
to end?

11 feet

Step-by-step explanation:

First, convert all the mixed fractions to improper fractions in the a/b form.

4 1/2 becomes 9/2 and 2 1/2 becomes 5/2.

Adding 9/2 to 5/2 we get (9+5)/2, which is 14/2 and that can be simplified to 7.

Finally, adding 7 to 4 we get 11.

So, the sum of the length of all three tables is just 11 feet long.

Hope this helps!

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

divide the numbers
