2. Starlight Tree Farm sells Douglas firs and Noble firs. One December they sold 139 more Douglas firs than Noble fir. The total number of trees sold was 277. Which equation could be used to solve for n, the number of Noble fir trees sold?

n - 139=377
n+139=377
2n-139=377
2n+139=377

x+ 189<-189;at most 70 pounds
x-70<-189; at most 119 pounds
x+70<-119;at most 189


Please HELP ME PLEASE!!! THE ONES WITH THIS <- ARE THE ONE'S WITH THE LINE UNDERNETH

Answer 1

I'm sorry to say that I only know number 1. Number one is 3 hours, only because if you need a total of 440 miles and you traveled 275 miles so far (which is 5hrs because 275 divided by 55 is 5). So you subtract those numbers (440 - 275) giving you 165. So to find out how many more hours you need, you divide 165 divided by 55 giving you 3hrs more to complete the destination.
