22x+1 where x would be Gail's age.
Formula of the area of a triangle = 1/2 b*h
(1/2)*10*6 = 30
M>5=m>4
m>5 and m>7 are on line then m>5+m>7=180
by substituting
m>4+37=180
m>4=143
m>2=m>7=37
m>4=m>8
m<3+m>5=180
1:60 because there is 60 seconds in 1 minute, so you'd have 70/x=1/60 and then you would cross multiply
