Soloha48 [4]2 years ago
4 0

Answer:

3.\ \dfrac{3x}{11x}, \dfrac{6}{22},  \dfrac{9}{33},\dfrac{12}{44}

4. -18\\5.\ 400

Step-by-step explanation:

<u>Solution 3:</u>

Equivalent fractions to are to \frac{3}{11} be found out.

<u>Method: </u> By Multiplying both the denominator and numerator with the same number, we can easily find equivalent fractions.

1. Multiply with 2:

\dfrac{3 \times 2}{11 \times 2}\\\Rightarrow \dfrac{6}{22}

2. Multiply with 3:

\dfrac{3 \times 3}{11 \times 3}\\\Rightarrow \dfrac{9}{33}

3. Multiply with 4:

\dfrac{3 \times 4}{11 \times 4}\\\Rightarrow \dfrac{12}{44}

If we try to write in variable form, it can be written as:

\dfrac{3x}{11x}

where x is any number.

---------------

<u>Solution 4:</u>

(2x-10) when x=-4

2 \times (-4) -10\\\Rightarrow -8 -10\\\Rightarrow -18

------------

<u>Solution 5:</u>

(10a)^2, a=-2\\\Rightarrow \{10 \times (-2)\}^2\\\Rightarrow (-20)^2\\\Rightarrow 400

If the measure of angle 2 is 92 degrees and the measure of angle 4 is (one-half x) degrees, what is the value of x?
zavuch27 [327]

Answer: x = 184°

Step-by-step explanation: As we can see in the figure below, angles 2 and 4 are <u>Vertical</u> <u>Angles</u>, i.e., they are angles opposite each other when two lines cross. Vertical angles are always congruent.

Then,

m∠2 = m∠4

92=x.(\frac{1}{2})

92=\frac{x}{2}

Value of x is

x=92(2)

x = 184

The value of x is 184°.
