The given expressions 7+ 7x ; 7 x + 1/7 are not equivalent or equal

to each other

Step-by-step explanation:

Let us firstly assume that 7 + 7x is equivalent ( to 7(x + 1/7) so that means

7 + 7x = 7(x + 1/7)

7 + 7x = 7x + 7(1/7)

7 + 7x = 7x + 1

7x + 7 = 7x + 1

Now, subtracting 7x from both sides, we get:

7x - 7x + 7 = 7x - 7x + 1

(7 - 7)x + 7 = (7 - 7)x + 1

(0)x + 7 = (0)x + 1 thus their occurs a false statement:

7 = 1 ( we know, 7 >1)

Thus we can say that

7 + 7x is NOT equivalent to 7(x + 1/7)

In this picture B and F are midpoints.

Pavlova-9 [17]

now, we know that B and F are midpoints, namely BF is a midsegment of the triangle, and therefore BF || AE, so, the base AE is twice BF.

$\bf 2BF=AE\implies 2(23)=5x-4\implies 46=5x-4\implies 50=5x \\\\\\ \cfrac{50}{5}=x\implies \boxed{10=x}$

The simplest form of the given expression $3\frac{11}{12} - 1\frac{4}{12}$ is $\frac{31}{12}$

Solution:

Given, expression is 3 11/12 – 1 4/12 $\rightarrow 3 \frac{11}{12}-1 \frac{4}{12}$

We have to find the simplest form of the value derived from the given expression.

Now, first let us solve the given equation.

$3 \frac{11}{12}-1 \frac{4}{12}$

converting mixed fractions to improper fractions.

$=\frac{3 \times 12+11}{12}-\frac{1 \times 12+4}{12}$

$\frac{36+11}{12}-\frac{12+4}{12}=\frac{47}{12}-\frac{16}{12}=\frac{47-16}{12}=\frac{31}{12}$

As there are no common terms to cancel it is in lowest form.

Hence, the lowest form of the given expression is $\frac{31}{12}$
