Starlight tree farms sells douglas firs and noble first one december they sold 139 more douglas first than noble firs the total number of trees sold was 377 which equation could be used to solve for n the number of noble fir trees sold n-139=377 n+139=377 this one 2n-139=377 2n+139=377 suppose you are driving to visit a friend in another state you are driving 55 miles per hour you must drive 440 miles total if you already driven 275 miles how long will it take to reach your destination use h to represent the number of hours it will take to reach your destination use the equation 55h+275=440 30 h 2 h 3 h this one 1 h

Part A:

Given that Starlight tree farms sells Douglas Firs and Noble First.

Let n be the number of Noble Fir trees sold, then if they sold 139 more Douglas First than Noble Firs, this means that the number of Douglas First trees sold is n + 139.

Given that the total number of trees sold was 377, then we have, n + n + 139 = 377, which means that 2n + 139 = 377

Therefore, the equation that could be used to solve for n, the number of Noble Fir trees sold is 2n + 139 = 377.

Part B:

Given that you are driving 55 miles per hour and you must drive a total of 440 miles. If you already driven 275 miles, then, the equation representing the number of hours, h, it will take to reach your destination is given by 55h + 275 = 440.

Subtracting 275 from both sides of the equation gives:



Dividing both sides by 55 gives:



Therefore, the time it will take you to reach your destination is 3 hours.

1.) 18+5 is one way i’m pretty sure there are others but i can’t think of them right now
