Answer:
So the question is asking you what of the two equations would you chose to solve for the variable. (which means what eqation is easier to solve and why)
Step-by-step explanation:
1) the first one is easier because you could multiple 2 or 5 to get 10 which is a nice number compare to 21 (the other eqaution)
2) the first one bc the second opption you would have a -7y +2 =x and thats a mouth full
3) the first one as well bc I work better with smaller numbers.

Answer:
80 degrees
Step-by-step explanation:
a line is always 180 degrees
one side of that line is 100
so, just subtract 100 from 180
you get 80
180 - 100 = 80
63 <= 7y
To solve for y just divide both sides by 7:
Y <= 63/7
Y <= 9
Because 63 is less than , you need to reverse the inequality sign.
The answer becomes y >=9
Now when you replace y with a number from 9 or higher the inequality will be true.
