Since you know the amount of what she earns you would use the number 15 and you dont know how long she worked you would put "x" next to the 15. so you would have 15x and then put a plus 5 to show her transportation fee. so you would have the equation of 15x+5:) and instead of x use h to show hours because h=hours
you feel me?
great!
Yes you can! Say you have 5(2 + x) + 3x. The answer would be 10+8x because when you use the distributive property you will end up getting 5*2 5*x and once you multiply, it's obvious 5 times 2 is 10 and 5 times x will equal 5x. Then you add 5x and 3x and get 8x. So, the simplified expression here is 10+8x. When you have this as an answer it's proving your answer right. You can without using the distributive property. We can have 10+5x+3x and it will be your simplified expression. It's the same thing with equations too.
Answer: B
Step-by-step explanation:
l = 2
2 ( l + w ) = 48 , or , l + w = 24
w = 8 , & , so , l = 2 w = 16 inches.
Answer: 3253
Step-by-step explanation:
Given : A test requires that you answer either part A or part B.
Part A consists of 7 true-false questions.
i.e. there are 2 choices to answer each question.
Now, the number of ways to answer Part A :
(1)
Part B consists of 5 multiple-choice questions with one correct answer out of five.
i.e. there are 5 choices to answer each question.
Now, the number of ways to answer Part B :
(2)
Now, the number of different ways to completed answer sheets are possible=
[Add (1) and (2) ]
