Jane pulled weeds in the garden 7 times . she was paid $5 each time she pulled weeds for less than 1 hour and $6 each time she pulled weeds for more than 1 hour. if jane received $39, how many times did she pull weeds for more than 1 hour?

The best way to answer this problem is to set up an equation.

So you know that $39 is the total, so lets say that since she pulled weeds 7 times, we'll let the amount of times represent T so the first step to the equation is to figure out how many times she pulled for less than an hour($5) and more than an hour($6). So that equation can be shown as (Tx$5)+(Tx$6)=$39. This should be a good start for you. It might be easier to try filling T in with different numbers that add up to 7 until the sets equal $39.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
