Answer:

61 3/5

Step-by-step explanation:

we realize that 8 4/5 can be written as [8 + (4/5)]

hence 7 x 8 4/5

= 7 x [8 + (4/5)]

= 7 [8 + (4/5)] (use the distributive property, see attached for reference)

= 7(8) + 7(4/5)

= 56 + 28/5 (convert 28/5 into mixed fraction)

= 56 + 5 3/5

= 61 3/5 (answer)

If f(x)=2x-4, what would be the answer if f(3)-1??

Vinil7 [7]

Answer:

Step-by-step explanation:

We have the function

$f(x) = 2x - 4$

and we want to know the value of $f(3) - 1$ .

The first step is to find $f(3)$ ; we can subtract 1 from it at the end! But what does $f(3)$ mean?

Basically, we're saying "what is the value of the function when $x = 3$ ?"

So, we simply replace $x$ with 3 in the function, and we get:

$f(3) = 2\times 3 - 4 = 2$ .

Finally, we subtract 1 to find $f(3) - 1 = 1$ .
