Melody stated that the sum of a positive and a negative integer equals a negative integer or 0.

(a) I'd say sometimes true. 3 + -7= -4 , -5 + 3= -2 , 8+-5=3, 7+-7=0

(b)  I'm not too sure about this one but I what i know is that if the positive number is higher than the negative number it will be a positive. If you are adding both a negative number and a positive number that is the same value it will be 0. And if you are adding a negative that is higher than the positive it will be a negative number. 

I hope this helped a bit.. (:

Answer:

Step-by-step explanation:

The purple circle, not ring is pi 7 squared = 153.93804

Then subtract the smaller circles area (pi 4 squared) = 153.9... - 103.6725576 =

50.2654824

Purple ring is 50.2654824

The entire circle is 4+3+3 (10) squared times pi = 314.1592654

( 50.2654824 / 314.1592654 ) x 100 = 15.999999998 %

78 is what percent of 110
irinina [24]

Answer: 70.909090909091%

Step-by-step explanation: Reading through the problem we have <em>78 is</em>, that's 78 equals, <em>what percent</em>, x/100, <em>of 110</em>, times 110.

It's important to understand that <em>percent</em> means over 100 so what percent would simply mean <em>x/100</em> or any variable but I will be using x.

So we have the equation 78 = \frac{x}{100} *110

So cross canceling the 110 and 100 to 11 and 10, we have 78 = \frac{11x}{10}

Multiply both sides by 10 to get rid

of the fraction and we have 780 = 11x.

Now divide both sides by 11 and 70.909090909091 = x.

So, 78 is 70.909090909091% of 110.
