Answer:
6. 51
7. 31
8. 20
Step-by-step explanation:
2x+8=110
2x=102
x=51
2x+x-3=90
3x-3=90
3x=93
x=31
7x+x+20=180
8x+20=180
8x=160
x=20
It's pretty straightforward and simple:
Six more means + 6.
Twice a number means 2n.
Is 16 means = 16
Now combine these three definitions and you will receive:
6 + 2n = 16
Now solve this simple equation:
6 + 2n = 16
2n = 16 - 6
2n = 10
n = 10 / 2 = 5
So the correct answer is D.
Answer:
<h2>All of the above</h2><h2 />
Step-by-step explanation:
Hope this doesn't happen to you
Whole numbers greater than zero are called positive integers<span>. Whole numbers less than zero are called </span>negative integers<span>. The </span>integer<span> zero is neither </span>positive<span> nor </span>negative<span>, and has no sign. Two </span>integers<span> are opposites if they are each the same distance away from zero, but on opposite sides of the number line.
ex. -10+-2 would be a negative integer you just add them and keep the sign
