Lindsay and lorraine are trying to match the jump rope world record. together, they need to jump 48 times in a row. lindsay has gotten 14 jumps in a row, and lorraine has gotten 13. how many more jumps (j) do they need to match the record? show your work!

For this case what we must do first is to obtain the total amount that both have accumulated.
 We have then:
 Lindsay has gotten 14 jumps in a row and Lorraine has gotten 13:
 14 + 13 = 27
 Then, we must find the remaining amount:
 j = 48-27
 j = 21
 
 they need 21 more jumps to match the record

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
