1. The number of packages the company needs to ship.
A family goes on a trip. They drive 65 mph. Write an equation using two variables to show the relationship between the number of hours driven, h , and the total amount of miles drive, m . How far did they drive after 7 hours?(1 point)
The equation to represent the relationship between the number of hours driven (h) and the total number of miles driven (m) is:
m = 65h
To find out how far they drove after 7 hours:
m = 65 * 7
m = 455
After 7 hours, they drove 455 miles.
m = 65h
To find out how far they drove after 7 hours:
m = 65 * 7
m = 455
After 7 hours, they drove 455 miles.
Which of the numbers 1, 2, and 3 is a solution of 2x+1≥7 ?(1 point)
Let's substitute each of the numbers into the inequality and check if they satisfy it:
For x = 1:
2(1) + 1 ≥ 7
2 + 1 ≥ 7
3 ≥ 7
This is not true.
For x = 2:
2(2) + 1 ≥ 7
4 + 1 ≥ 7
5 ≥ 7
Again, this is not true.
For x = 3:
2(3) + 1 ≥ 7
6 + 1 ≥ 7
7 ≥ 7
This is true.
Therefore, the number 3 is the solution of the inequality 2x + 1 ≥ 7.
For x = 1:
2(1) + 1 ≥ 7
2 + 1 ≥ 7
3 ≥ 7
This is not true.
For x = 2:
2(2) + 1 ≥ 7
4 + 1 ≥ 7
5 ≥ 7
Again, this is not true.
For x = 3:
2(3) + 1 ≥ 7
6 + 1 ≥ 7
7 ≥ 7
This is true.
Therefore, the number 3 is the solution of the inequality 2x + 1 ≥ 7.
