Answer:

  x = 29

Step-by-step explanation:

Follow the directions: substitute 13 for y in the first equation.

  x + 13 = 42

Subtract 13 from both sides of the equation.

  x +13 -13 = 42 -13

  x = 29

Help please, not sure how to do this...​
olga nikolaevna [1]

Answer:

8.38

Step-by-step explanation:

The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.
