Answer:
N/A
Step-by-step explanation:
The first equation doesn't make any sense.
Answer:
The first one: if 2/3 is 12 then 1/3 is 6. 3/3 is 18. SO Jane had 18 stuffed animals before the donation.
The second one: 25 students then 13 are men so 25-13 is 12. 12/25 as a percentage is 48%
Hope this helps!
Answer:
45
Step-by-step explanation:
If you write it out it will look like this, 2x+45+x=180
3x+45=180
3x+45=180
-45 -45
3x=135
/3 /3
x=45
Answer:
x = 7
Step-by-step explanation:
3x - 2 and 2x + 5 are alternate interior angles and congruent, thus
3x - 2 = 2x + 5 ( subtract 2x from both sides )
x - 2 = 5 ( add 2 to both sides )
x = 7
If x = 7 then a and b are parallel
