Hence, the value of x = 21.
i have it on negative 3 and positive 4
y=-3x+4 graphed looks like this.
Remeber y=mx+b, m is the slope, and b is the y-intercept.
Answer: Each book weighs 2.5 pounds.
Step-by-step explanation: 75 divided by 2.5 is 30. Or you could also get the answer by multiplying 30 and 2.5 which it would be 75. So, therefor, the answer is 2.5.
To find the weight of each textbook, we divide the total weight by the number of books. Therefore, each book weighs 2.5 lb.
If thirty copies of a textbook weigh a total of 75 lb, to find the weight of each individual book, we need divide the total weight by the number of books.
Here is a step-by-step explanation of the solution:
