Put in slope intercept form so the first equation would be y=-x-9 then the second one will be y=-5/2x-16
Step-by-step explanation:
hope this helps. in the first part you set the problems equal to each other. in the second, you get rid of one letter, then solve.
25
If 15 is 60% of a number, it is 3/5 of the whole. Since 5 goes into 25 5 times, and 5 goes into 15 3 times, 15 is the 3/5 of 25.
