Determine if the expressions are equivalent: 7+ 7x; 7 x + 1/7

Mathematics

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

<u>to each other </u>

<u />

<u>Step-by-step explanation:</u>

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

<u>7 + 7x is NOT equivalent  to 7(x + 1/7)</u>

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}

<u>Solution:</u>

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}
