44
Assuming JM and LN are parallel, KMJ=MKN. MKN is part of a triangle where the other two values are defined (48 and 88). By subtracting these values from 180, we find the value of MKN is 44, which therefore is also the value of KMJ.
20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.
Now lets work this out.
20 + 25x =282.50
25x = 262.50 (subtract both sides by 2 to get the x's alone)
x = 10.5 (divide both sides by 25 to get just x)
x = 10.5 hours
So the answer is A.
Answer:
x=17/13
Step-by-step explanation:
-3(3x-3)=4/5(5x-10)
-9x+9=4x-8
-13x= -17
x=17/13
Answer:
23/12
Step-by-step explanation:
2 1/2 = 5/2(3/3) = 15/6
1 1/3 = 4/3(2/2) = 8/6
15/6 - 8/6 = 7/6
7/6(1/2) = 7/12
16/12 + 7/12 = 23/12
