Step-by-step explanation:
Using absolute value to tell wether the sum of two integers is positive or negative.
Suppose we have a positive integer,
x and a negative interger, -x and we want to find their sum, we take the absolute values of each of the integers, that is |x| and |-x|. Then we subtract these values: |x| - |-x|. If the larger integer is positive, the result of the difference is positive, but if the larger number is negative, the result of the difference is negative.
For any integer x, x + (-x) = 0
Answer:
A=30
Step-by-step explanation:
We know through the Angle Sum Property of A Triangle that
all its angles add up to 180 degrees
Hence, A + (a+b) +B= 180
A+100+50=180
A+150=180
A=30
Slobs, can you answer my question when you're done?
Answer:
367.6
Step-by-step explanation:
Hope this helps!
91 + (10x - 4) + (8x + 3) = 180
91 - 4 + 3 + 10x + 8x = 180
90 + 18x = 180
18x = 180 - 90
18x = 90
x = 90/18 = 5
x is 5
