Answer: 
=
=
Step-by-step explanation:
In order to get from 8 to 56, we have to multiply by 7.
We always do the same to the top! 3 multiplied by 7 = 21.
In order to get from 7 to 56, we have to multiply by 8.
We always do the same to the top! 3 multiplied by 8 = 24.
Equation:
distance + distance = 2250 miles
3x + 3(x-110) = 2250
6x - 330 = 2250
6x = 2580
x = 430 mph (rate of the westbound plane)
x-110 = 320 mph (rate of the eastbound plane)

Answer:
70cm
Step-by-step explanation:
,
Since, both of the tank posses the same quantity of water then there volume is the same thing
For rectangular base
Volume= (Lenght × breadth × hheight)
If we substitute values
Lenght= 80 cm
Breadth= 70 cm
height= 45 cm
Volume= 80cm × 70cm × 45cm
Volume= 252000cm^3
For square base
Volume= (side)^2 × height
side =60cm.
But volume of square base= volume of
rectangular base
252000cm^3= 60^2 × height
Height= (252000cm^3)/(60^2 )
Height= 70 cm
Hence, the second tank is 70 cm deep
Sharon's age= 2x
Brian's age= x
(2x-5)+(x-5)= 25
3x-10=25
3x=15
x=5
Brian is 5 years old and Sharon is 10
