Answer:
x = 15
Step-by-step explanation:
Given
See attachment
Required
Find x
The figure in the attachment is a quadrilateral and the angles in a quadrilateral add up to 360.
So, we have:
90 + 6x + 5+ 10x - 40 + 4x + 5 = 360
Collect like terms
6x + 10x + 4x = 360 - 90 - 5 + 40 - 5
20x = 300
Divide both sides by 20
x = 15
Hence, the value of x is 15
Answer:
The car is going 45 mph
Step-by-step explanation:
Since the speed limit is 35 mph and the car is 10 mph over the speed, we can add them to find out how fast the car is going. We can solve 35+10 which will give us 45. So it is not a sum of 0 but instead a sum of 45.

She had 47$.
She then writes a check for $55 and give it away.
47-55=-8.
Her balance will be $-8
Answer:
29/12
Step-by-step explanation:
hello :
2/3 +5/6 +11/12 = (2×4)/(3×4) + (5×2)/(6×2) + 11/12
2/3 +5/6 +11/12 = 8/12 +10/12 +11/12 = (8+10+11)/12
2/3 +5/6 +11/12 = 29/12
