Answer:
13.75
Step-by-step explanation:
Slash and dash. turn the both minuses into positives and add like normal. 6.5 plus 7.25 equals 13.75.
C. For every decrease of one chore completed, one hour was spent on the internet.
When adding fractions you need to get common denominators then you multiply too times bottom and then boom add and there you go
1: 5 2: 9 or 10
For question 1 we can round 115 to 100, 5x100 is 500 which is closer to 545 than 7x100 = 700.
M=30° because the right angle and 60 degree angle equal 150 and 180 (degrees in a triangle) minus 150 is 30
n=50° because 40 plus the right angle is 130 then the difference between that and 180 is 50 then n is the vertex angle of the one you found
t=98° because answer n plus the other part to the straight angle including the 112° angle is 68 then the total angle turns to 118 then the final angle turns to 62 via earlier reasoning, then because of another straight angle t=98
use the earlier reasoning to fine the other answers of
p=71°
q=39°
use the angle degrees formula to get Pentagon's maximum angles then use earlier resources
the final answers u should be able to figure out from there and u will never learn unless you do some yourself
