Answer:
280
Step-by-step explanation:
400 - 120=280
280= number of children lost
Y=-2/11x-5/11 is the slope intercept form
3 is the greatest common denominator
You have to plug in 7 for f and 8 for k making it look like -5(7)-2+8-3(8), now multiply to get the further more, -35-2+8-24, now add or subtract to get -53
