The answer is 1 2/8
3 \frac{1}{8}  - 1 \frac{7}{8}  =  \frac{25}{8}  -  \frac{15}{8}  =  \frac{10}{8}  = 1\frac{2}{8}

Answer : The answer of the expression 3\frac{1}{8}-1\frac{7}{8} is, 1\frac{2}{8}

Step-by-step explanation :

Mixed number : It is a combination of a whole number and a fraction.

As we are given the expression.

3\frac{1}{8}-1\frac{7}{8}=?

Now we have to determine the value of this expression.

3\frac{1}{8}-1\frac{7}{8}

First we have to convert the mixed fraction into fraction form.

3\frac{1}{8}=\frac{25}{8}\\\\1\frac{7}{8}=\frac{15}{8}

So,

\frac{25}{8}-\frac{15}{8}

Now taking LCM, we get:

\frac{25-15}{8}

\frac{10}{8}

Now written in mixed fraction.

1\frac{2}{8}

Thus, the answer of the expression 3\frac{1}{8}-1\frac{7}{8} is, 1\frac{2}{8}

If ƒ(x) = x − 4 and g(x) = 3x + 5, find (ƒ + g)(x).
siniylev [52]

Answer:

(f+g)(x)=4x+1

Step-by-step explanation:

We are given the two functions:

f(x)=x-4\text{ and } g(x)=3x+5

And we want to find:

(f+g)(x)

This is equivalent to:

=f(x)+g(x)

By substitution:

=(x-4)+(3x+5)

Rearranging yields:

=(x+3x)+(-4+5)

Combine like terms:

=4x+1

Hence:

(f+g)(x)=4x+1
