The equation service fee + hourly fee = the total fee 20 + 25x = 282.50Solving the equation 20 + 25x = 282.50 25x = 282.50 - 20 25x = 262.50 x = 262.50/25 x = 10.5 The plumber completes his job in 10.5 hoursThe answer is option a.
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:
negative integer
Step-by-step
above answer is correct
Answer:
A)2x+7=38
2x=38-7
2x=31
x=31/2
x=15.5
B)3x-8=52
3x=52+8
3x=60
x=60/3
x=20
C)34%of 68
34/100×68
0.34×68
=23.12
Working step by step I first see all my different groups then add them all together so 12 - cats 15 - dogs 6 - both 9 - neither 12 students + 15 students + 6 students + 9 students = 42 students therefore 42 students are in the class 16 + 10 + 3 + 12 = 41 I’m sorry if i got it wrong!
