The equation would be 35x +10 = 150
35x =140 (subtraction property)
x = 4
Answer: she worked for 4 hours

Hi there,
From what I can understand from your question,
35x + 10x= $150
45x= $150
x= $150 / 45
  = 3.333333 hrs
  = 3 1/3 hrs
Pardon me if this is wrong

Hope this helps:))

Answer:

162

Step-by-step explanation:

20736 x 729 x 4/216 x 64 x27

Now go ahead and do the cancellations

20736/216 =96

729/27 =27

64/4 =16

so you end up getting 96 x 27 x1 /26

96/16 =6

so you get 27 x 6 =162
