ans
here let mary age be x and fred be y
1st equation
x= 5y
2nd equation
x+3 =4(y+3)
now from 1st equation putting value of x in equation 2
x+3 = 4y+12
5y+3 = 4y +12
y = 9
so fred is 9 and mary is 45
Answer:
x<-1 or x>=5
Step-by-step explanation:
there is an open circle at -1
an open circle means it is not equal to
the line goes to the left which means x is less than
x < -1
there is a closed circle at 5
a closed circle means equal to
the line goes to the right which means x is greater than
x>= 5
the line looks like boat oars
so this is a compound inequality using or
x<-1 or x>=5
Area of cone = 1/3 base area x height
Area of cone = 1/3 (16π) x 9
Area of cone = 48π ft³ or 150.8 ft³
Answer:
Step-by-step explanation:
ok...so she leaves Orlando at 11:05 am.....the flight takes 5 hr and 17 minutes..
11:05 am + 5 hrs = 4:05 pm.....4:05 + 17 minutes = 4:22 pm.
so she arrives at 4:22 pm eastern time....(orlando time)...but Las Vegas is pacific time
so if 12 pm eastern = 9 am pacific.....a difference of 3 hrs
so the local time in Las Vegas when her plane lands is :
4:22 pm - 3 hrs = 1:22 pm <===
