3x + 7 = 35 Tell me what you would do for the first step

Jim makes $10.35 per hour. write an equation that jim can use to calculate his pay.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?
