Find the value of x for which line a is parallel to line b. (21)

Mathematics
1 answer:
Romashka [77]3 years ago

X is 20 degrees. Since it says that lines a and b are parallel and angles four and five are right next to each other, it means that when you add the two of them together you’ll get 180. Since it’s replaced with variables with coefficients, add the coefficients to get 9 and divide 180/9 to get 20. 20 is the value for x which is your answer

Find the variation constant and an equation of variation for the given situation.
Angelina_Jolie [31]

Answer:

\displaystyle y=14\cdot x

Step-by-step explanation:

<u>Directly Proportion</u>

It's said that y varies directly proportional as x, if:

y=k\cdot x

Where k is a constant of proportionality.

We know that y=7 when x=1/2.

Using the above condition, we can find the value of k:

\displaystyle 7=k\cdot \frac{1}{2}

Solving for k:

k=14

Thus, the equation is:

\boxed{\displaystyle y=14\cdot x}

Find the least common denominator for these fractions. Enter your answer in
Tju [1.3M]

Answer:

LCD = 12

Equivalent Fractions with the LCD

5/6 = 10/12

5/4 = 15/12

Step-by-step explanation:

Rewriting input as fractions if necessary:

5/6, 5/4

For the denominators (6, 4) the least common multiple (LCM) is 12.

LCM(6, 4)

Therefore, the least common denominator (LCD) is 12.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

5/6 = 5/6 × 2/2 = 10/12

5/4 = 5/4 × 3/3 = 15/12

I used a least common denominator calculator so I hope this helped!!
