A pet shop has a total of 17 dogs and birds. Altogether there are 48 feet. How many dogs are there
and how many birds?
A) 7 dogs and 10 birds B) 9 dogs and 8 birds
C) 6 dogs and 11 birds D) 8 dogs and 9 birds
I got the answer C is this right?
Nope. For C, I only count 46 legs.
Here's something you can do to get the answer:
1) multiply the number 4 with the number I'd dogs becuase they have 4 legs.
2) multiply the number 2 with the number of of birds because they only have 2 legs.
3) add the numbers you ended up with to see if they add up to 48. If it equals 48, then it is the answer.
Thank you this was a big help I got
4(7)=28 +10(2)+=20
28+20=48=A
Right.
To solve this problem, we need to set up a system of equations based on the given information.
Let's assume that the number of dogs is represented by 'D' and the number of birds is represented by 'B'.
From the first sentence, we know that there is a total of 17 dogs and birds: D + B = 17.
From the second sentence, we know that the total number of feet is 48. Since dogs have 4 feet and birds have 2 feet, we can express this as the equation: 4D + 2B = 48.
Now we have a system of two equations:
Equation 1: D + B = 17
Equation 2: 4D + 2B = 48
To find the values of D and B, we can solve this system using different methods like substitution or elimination.
Let's use the method of substitution:
From Equation 1, we can express B in terms of D as B = 17 - D.
Substituting this into Equation 2, we get:
4D + 2(17 - D) = 48
4D + 34 - 2D = 48
2D + 34 = 48
2D = 48 - 34
2D = 14
D = 14/2
D = 7
Substituting this value of D back into Equation 1, we can find B:
7 + B = 17
B = 17 - 7
B = 10
Therefore, there are 7 dogs and 10 birds. So, the correct answer is A) 7 dogs and 10 birds.
