y=70(vertically opposite angle)
70+50+X =180 (sum of angles in triangles)
120+x=180
X=60 //
Answer: A 40 feet
Explanation:
If a building is 380 feet tall and the elevator has to descend 420 feet to get to the underground parking garage. So 420 - 380 to remove the height of the building from the equation. This would give us 40 feet underground left until the elevator reaches its desired destination.
Answer:
x = 10
Step-by-step explanation:
=> 4x + 1 + 2x = 61
=> 6x = 61 - 1
=> 6x = 60
=> x = 60/6
=> x = 10
<u>Hence</u><u> </u><u>the</u><u> value</u><u> of</u><u> x</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u> </u><u>.</u>
Answer:
39
Step-by-step explanation:
<u>Data</u>
- standard deviation (sd) = 2
The z-score is computed as follows:
z = (x - mean)/sd
where x is a value of interest, in this case, the missing data value. Replacing with data and solving for x:
-2.1 = (x - 43)/2
-2.1*2 + 43 = x
39 = x
10. 5c+4c+c=5+4+1 you get one because when have a unsolved variable it is automaticlly 1. so it solves out to be 5x1+4x1+1=10.
