The mass of the regular hippo at birth to that of the pygmy hippo is 49/11
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.
The pygmy hippo had a mass of 5 1/2 kg at birth = 5.5 kg.
The regular hippo had a mass of 24 1/2 kg at birth = 24.5 kg
Hence:
Ratio of regular hippo to pygmy hippo = 24.5 / 5.5 = 49/11
The mass of the regular hippo at birth to that of the pygmy hippo is 49/11

Answer:
x=4 y=3
Step-by-step explanation:
y=x-1
2x-3y=-1
put x-1 in for y and solve
2x-3(x-1)=-1
2x-3x+3=-1
-x+3=-1
-x=-4
x=4
put 4 in for y and solve
y=4-1
y=3
First, we have to get the variable to one side of the equation, which can be done with simple subtraction.
4x -3 (-6x) = 6x + 9 (-6x)
-2x -3 = 9
now just solve as a regular equation:
-2x - 3 = 9
-2x = 12
x = -6
so, x is equal to -6
