Slope is negative for each...Remember Y-int and rise/run for slope.
Y=mx+b
Y= -2/3X - 2
Y= -5/2x + 2
suppose the number of boy is x ,so the number of girls is 5/4x,so the total number is 9/4x,we knew the number of total students is 36,so 36=9/4x,x is 16.
Answer:
c = 7.5 meters.
Step-by-step explanation:
hello :
use phtagore - rule :
c² = 6²+4.5²
c² = 36 + 20.25
c² =56.25
c = √56.25
c = 7.5 meters.
#7 is 3
#8 is 4
#9 is 4
#10 is 3
#11 is 5
#12 is 3
40 plus 40 50 plus 50 would be 180 so the awnser is 180
