Yes. Their sum can be equal to 1 because if they have the same denominator they will add easier like 3/4 and 1/4 or 1/2 and 1/2. All of them have the same denominator and still equal 1

The answer is 73.33333333 (repeated). You can also write it as 73 or 73.3 with a line over the 3 (after the decimal point) to indicate it being repeated.

In ABC, what is the value of x?<br><br> Pls hurry im on a time limit here
kiruha [24]

Answer:

70

Step-by-step explanation:

By exterior angle theorem:

(2x + 12) \degree = 112 \degree + 180 \degree - 2x \degree \\  \\ (2x + 12) \degree = 292 \degree - 2x \degree \\  \\ (2x + 12) \degree  + 2x \degree = 292 \degree \\  \\ (2x + 12 + 2x) \degree = 292 \degree \\  \\ (4x + 12) \degree = 292 \degree \\  \\ 4x + 12  = 292  \\  \\ 4x = 292 - 12 \\  \\ 4x = 280 \\  \\ x =  \frac{280}{4}  \\  \\ x = 70

PLEASE HELP W/ THIS ASAP!!

Answer:

- 1.375

Step-by-step explanation:

Each dot is worth -1/8 of a unit when moving left.

So the coordinates of the dark dot are - 1 and - 3/8

or - 1.375 . The word coordinates (plural) bothers me. It all depends on how you have been asked to represent these points. Another possibility is (-1.375,0). You have to choose from the examples you have been given. I wouldn't do that because you have not been given and xy graph.
