Tyler is 9 years old his sister Olivia is 6 years less than twice his age writ a numerical expression for Olivia’s age
liberstina [14]
Hello there!

The following will show you

T = tyler

O = olivia


O = 2t - 6

when you include numbers, it is represented by:

O = (2 * 9) - 6

Now, let's solve this to find out just how old Olivia is.

2 * 9 = 18

18 - 6 = 12

Olivia is 12

This means that olivia is 3 years older than tyler

I hope I helped!

What’s the answer to 9 and 10???
Zigmanuir [339]

Answer:

9. C. division

10. D. addition

Step-by-step explanation:

When solving for X the goal is to get it all by itself on one side of the equation and to do that you have to undo the operations already in effect on it.  In number 9 the x is multiplied by 3 so to undo that you would need to divide by 3 and that would cancel out leaving the x by itself.  Then you would need to divide by 3 on the other side of the equation also to keep it balenced.  In number 10 the X is connected to the 10 through subtraction so to cancel that out you would subtract 10 from both sides to get the X alone.

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Ugo [173]

Answer:

31 degrees

Step-by-step explanation:

Measure angles 1 and 3 are vertical angles, meaning they are equal which means 3 = 149 degrees

Angles 2 and 3 are adjacent and supplementary, meaning that their angles add up to 180.

1<u>8</u>0 - 149 = 31 degrees
