7 4/5 feet long because 20 2/5 can't be subtracted by 12 3/5 so you change 20 2/5 to 19 7/5. 19-12=7 and 7-3=4 so the answer is 7 4/5 feet long
Answer:
E) 150°
Step-by-step explanation:
angle adjacent to 70° angle is 110°
the angle supplemental to 'x' must be 180-(40+110) or 30°
this means 'x' must be 150°
The missing number for the subtraction of matrices is 4.
<h3>
How to subtract the matrices?</h3>
The subtraction of two matrices of the same size is really direct. You just need to subtract the elements that are in the same position, then:
Then the missing therm will just be equal to the difference between the last two elements of each matrix:
-2 - (-6) = -2 + 6 = 4
The missing number is 4.

Answer:
x> 30
Step-by-step explanation:
+ First, is the inequation 3x - 52 > 28.
+ If Yes, so we can solve:
3x - 52 > 28
3x - 52 + 52 > 28 +52
3x > 90
3x/3 > 90/3 (divide both sides by 3>0)
x > 30
