So say for example u have -7 - (-5), think of subtracting integers as adding the opposite, so ur adding the opposite of -5, the opposite of -5 is 5, so ur adding -7 and 5= -2
another one: -15 - (-18)
again, adding the opposite. -15 plus positive 18= 3
Answer:
x=72
y=54
Step-by-step explanation:
1st question. y=54 because it is a bisector of the 108 degree angles. (a polygon's interior angles add to number of sides minus 2 times 180)
There are two ys, so they add up to 108. A triangle's interior angles add to 180. 180-108 =72 x=72
2nd question, x is 72 ( it says x is the same measure) so 180-72=2y.
y still equals 54
<span>x^2+6x+11=0
After solving this u will bet
X=-6+,-</span>√-8/2
So roots of a equation are imaginary
<span>In the question "Complete the following equation using <, >, or =. 100% ___ 1" The correct answer is 100% = 1. A percentage is a number or ratio expressed as a fraction of 100. To convert a given percentage to its equivalent number, we divide the given percent by 100. Therefore, 100% = 100 / 100 = 1.</span>
