Consecutive interior theorem
X+96+96+x= 180
2x+192=180
2x= -12
X=-6
An integer is just a whole number, so like 3 or 6 or 17. any number without a decimal.
The question is asking what number is less than 2 and 8.
the answer could be 5 or 3 or 4
X=2 or -7(answer choice A)
How can I send you the drawn representation on number line ?
25)
z + 4 >= 2z
-z >= -4
z <= 4 (you flip the sign when you divide over negative number)
on number line: from 4 to -infinity
you use normal arithmetic like equations
29)
-9 + 2a < 3a
-9 < a (just one step done)
on number line from -9 to infinity
41 and 43 ? not in the page
