The measure of RST can be represented by the expression (6x + 12)°. What is mRST in degrees?


78°

84°

120°

156°

Answers

Answer 1
Answer:

The measures of RST in degrees is 120degrees

Lines and angles

From the given diagram, the following expression is true

<RST = 78 + 3x - 12

Since <RST = 6x +12, hence;

6x + 12 = 66 + 3x

3x = 54

x = 18

Find the measure of <RST

<RST = 6(18) + 12
<RST = 120degrees

Hence the measure of RST in degrees is 120degrees

Answer 2
Answer:

Answer:

The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m<RST=(6x+12)\° -----> equation A

m<RST=78\°+(3x-12)\° -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

6x-3x=78\°-24\°

3x=54\°

x=18\°

The measure of angle RST is equal to

m<RST=(6(18)+12)=120\°

What is the fraction for 2.3125? Improper fraction form

Answers

The fraction equivalent of 2.3125 in improperfraction form is 165/80.

We have,

To convert the decimal 2.3125 into an improper fraction, follow these steps:

- Identify the whole number part:

In this case, the whole number part is 2.

- Determine the fractional part:

The fractional part is the decimal part of the number. In this case, the decimal part is 0.3125.

- Convert the decimal part to a fraction:

To convert the decimal 0.3125 to a fraction, count the number of decimal places, which is four.

Then, write the decimal part over a denominator of 10 raised to the power of the number of decimal places.

0.3125 = 3125/10,000

- Combine the whole number part and the fractional part:

Add the whole number part to the fraction obtained in step 3.

= 2 + 3125/10,000

- Simplify the fraction if possible:

In this case, the fraction 3125/10,000 can be simplified by dividing both the numerator and denominator by 125, which is the greatest common divisor.

= 2 + 3125/10,000

= 2 + (3125 ÷ 125) / (10,000 ÷ 125)

= 2 + 25/80

- Convert the mixed number to an improper fraction:

Multiply the whole number part by the denominator of the fraction and add the numerator.

Place the result over the denominator.

= 2 + 25/80

= (2 x 80 + 25) / 80

= 165/80

Thus,

The fraction equivalent of 2.3125 in improperfraction form is 165/80.

Answer: The answer is 2(5)/(16).

Step-by-step explanation: Step 1. Let's rewrite the decimal number as a fraction with 1 in the denominator: (2.3125)/(1).

Step 2. Multiply to remove 4 decimal places. Here, you multiply top and the bottom by 10⁴=10000: (2.3125)/(1)*(10000)/(10000)=(23125)/(10000).

Step 3. You find the Greatest Common Factor of 23125 and 10000, or if it exists, and reduce the fraction by dividing both numerator and denominator by the GCF=625: Numerator: 23125÷625=37

Denominator: 10000÷625=16.

Last but not least is step 4. Simplify the improper fraction: 2(5)/(16). Now in conclusion: 2.3125=2(5)/(16). I hoped this step-by-step explanation will be helpful! Can you give me brainliest? I will be appreciated! :D

The graph of a linear equation may not be a straight line.

Answers

If this is a true false question. The answer is false. The idea behind a linear equation is that it is a straight line. Proof for this is the y=mx+b equation. Where m defines a constant slope(or in other words, a straight line) and b represents how high the line appears.
As you can see there is nothing that could bend the line into a more curvy shape (things that do bend are polynomials and such)
