The number is 18.
In order to find this, we need to take each side and turn them into mathematics statements.
Five times the sum of a number and 3.
5(x + 3)
3 times the difference of twice the number and 1
3(2x - 1)
Now that we have these, we can set them equal to each other and solve.
5(x + 3) = 3(2x - 1) ----> Distribute
5x + 15 = 6x - 3 -----> Subtract 5x from both sides
15 = x - 3 -----> Add 3 to both sides
18 = x
Answer:
50%
Step-by-step explanation:

Answer:
- y = 0
- A all real numbers
- E y > 0
- infinity
Step-by-step explanation:
1. The horizontal asymptote is the y-value the function approaches, but does not reach. That value is y = 0. This equation is the equation of that asymptote.
__
2. The domain is the horizontal extent of the graph. It covers "all real numbers." (A)
__
3. The range is the vertical extent of the graph. As we said in part 1, the value y = 0 is never reached, so the vertical extent (range) is y > 0 (E).
__
4. The graph extends upward indefinitely as x extends to the left indefinitely. That is, y → infinity.
32 divided by 4 is 8. so 8 miles per gallon.
Answer: 7(n + 4)
Step-by-step explanation:
I'm not sure how to explain this one, but I'll try:
Seven times the sum of a number, n, and four
7 times n + 4 (sum means addition)
