Answer:
15t+9r=2
Step-by-step explanation:
the terms which are the variables are not the same on any part of the equation
Melanie has 137 dollars in total.
Let each book cost=x
No of books=17
So total cost of 17 books=17x
After buying books Melanie left with 11 dollars
According to question the required equation will be=
17x+11=137
17x=137-11=126
x=8
i.e Price of each book is 8 dollars. (Answer)
The correct answer is 15
<span>4 + (x/3) = 9 </span>
<span>(x/3) = 9 - 4 </span>
<span>(x/3) = 5 </span>
<span>x = 15 </span>
Answer: 2. c 3. d
Step-by-step explanation:
Answer: The expression which must fill in each blank space to complete step 3 is; Choice B; Cos(A)Cos(B).
Which expression must fill in each blank space?
From the task content; It follows that the mathematical evaluation is in a bid to derive the Trigonometric identity for Tan (A-B).
From observation, it follows that the required expression is; cos(A)sin(B). This is because upon division of each term by the expression, the result is as in Step 4.
