A farmer has both sheep and chickens on his farm. All the animals have the expected number of parts. When his animals are all
lora16 [44]

Answer:

13 sheep, 19 chicken

Step-by-step explanation:

You can start to solve this problem by assigning variables. First, let's assign the number of sheep there are as x and the number of chickens there are as y.

Because each sheep has 4 legs, the number of legs for each sheep would be 4x. Similarly, because each chicken has 2 legs, the number of legs for each chicken would be 2y. Each animal would have 1 head, so the number of heads would just be x and y. Because the number of legs in total are 90, 4x + 2y=90. Because the number of heads in total are 32, x+y=32.

There is now a system of equations with two unknown variables and two equations. There are many ways to solve this, but for me, the easiest would be elimination. First, I would double the second equation, 2x+2y=64. Then, I would subtract that from the first equation, eliminating y. 2x=26. Solving for x gives 13. We can then plug that value into the second equation, making y be 32-13=19. This means that x=13 and y=19, meaning that there are 13 sheep and 19 chicken.

VLD [36.1K]

Answer:

Step-by-step explanation:

Part A: 5/26

Part B: 5/26+ 1/2 which is 18/26 or 9/13

Part C: 5/26 +21/25. 'without replacing' means there is one less option in the bag. So denominator becomes 26-1=25. Numerator is 21 because there are a total of 21 consonants in the alphabet. Since we removed a vowel and not a consonant, it will remain 21.
