Answer:
Step-by-step explanation:
132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have 540 degrees. Remove the brackets.
132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540 Collect like terms
13x + 241 = 540 Subtract 241 from both sides.
13x = 540 - 241
13x = 299 Divide by 13
x = 299/13
x = 23
<P = 4x + 2
<P = 92 + 2
<P = 94

Answer:
The plumber worked 50 hours, and his assistant worked 25 hours.
Step-by-step explanation:
Since a plumber and his assistant work together to replace the pipes in an old house, and the plumber charges $ 30 an hour for his own labor and $ 20 an hour for his assistant's labor, and the plumber works twice as long as his assistant on this job, and the labor charge on the final bill is $ 2000, to determine how long did the plumber and his assistant work on this job the following calculation must be performed:
40 x 30 + 20 x 20 = 1200 + 400 = 1600
50 x 30 + 25 x 20 = 1500 + 500 = 2000
Therefore, the plumber worked 50 hours, and his assistant worked 25 hours.
in decimal formation it is -0.5 and in fraction -1/2
