Answer:
50/7.
Simplified to 7.14.
Step-by-step explanation:
Combine like terms, 5x and 9x.
5x+9x=14x
14x = 100
14x / 14 = 100 / 14
x = 50/7 or 7.14
Hope this helps!

Answer:
Construction of perpendicular to line <em>m</em> is shown in image attached
Step-by-step explanation:
Steps For construction of perpendicular on line <em>m</em> from from point <em>P:</em>
1) Open a compass more than a half the length of line <em>m</em>.
2) From one end of the line mark man arc on above the line.
3) Now, from the another end construct another arc cutting the previous arc. Name this point of intersection as <em>Q.</em>
4) Finally draw straight line from point <em>Q</em> through <em>P</em> to the line m.
5) Construction of perpendicular to line <em>m</em> is shown in image attached.

Answer:
C. 2.937
Step-by-step explanation:
Given the following :
H0 : p = 0.25
H1 : p > 0.25
Number of observations (n) = 647
p' = 30% = 0.3
SD = sqrt[(p(1 - p) / n)]
1 - p = 1 - 0.25 = 0.75
SD = sqrt[(0.25 * 0.75) / 647]
SD = sqrt[0.0002897]
SD = 0.0170234
Z = (p' - p) / SD
Z = (0.3 - 0.25) / 0.0170234
Z = 0.05 / 0.0170234
Z = 2.9371187 = 2.937
