One number is 4 more than another, and their sum is 60. what is the smaller number?

if x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?

x + y = 60 and -x + y = 4
x + y = 60 and x - y = 4
x + y = 60 and x + y = 4

The graph and table shows the relationship between y, the number of words jean has typed for her essay and x, the number of minutes she has been typing on the computer. according to the line of best fit, about how many words will jean have typed when she completes 60 minutes of typing? 2,500 2,750 3,000 3,250

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
