If there are $22 made per hour for 7 hours, you’d add 22 per hour in your table. 1 hour=$22, 2 hours=$44, 3 hours=$66, and so forth. make a table of these numbers up to 7 hours.
700,000+2,000+1, should be your answer.
Questions 1 and 2 are correct.
Question #3 is A
Question #4 is C
Question #5 is C
-4x - 7 +10x = -7 + 6x
Combine like terms on left side.
6x - 7 = -7 + 6x
Add 7 to both sides.
6x = 6x
Subtract 6x from both sides.
0 = 0
This means there are infinitely many solutions.
