Respuesta :
32lbs. You take 4 and multiply it by 8 which gives you 32, the dog weighs 32lbs, then you have 8 left over, the cat weighs 8lbs.
The weight of the dog will be 32lbs.
How to form an equation?
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say
Weight of Terris dog = G
Weight of Terris cat = C
Given that,
her dog weighed 4 times as much as her cat
So,
D = 4C
and
Together the pets weighed 40lbs.
So,
D + C = 40 lbs
Now substitute D = 4C into second equation
4C + C = 40
5C = 40
C = 8 lbs
Now,
Substitute this 8 lbs into the first equation
D = 4(8) = 32 lbs
Hence, The weight of the dog will be 32lbs.
