First error is that the legs are a and b so a should be x and b is 6 and c is 10 the second error is at the end they did not take the square root to get x by itself the real answer should be
X^2 +6^2=10^2
X^2+36=100
X^2 =64
X=8
9:45 plus 3 hours goes to 12:45 pm. add 45 minutes you get 1:30PM as your answet
The answer is 30. 360/12.
2 2/3 x 3/11
= 8/4 x 3/11
= 24/44
Simplified
6/11
1.25*(t)+7=43.25
To solve the 2nd one, you must do 43.25 - 7 = 26.25
36.25 divided by 1.25 = 29
