Answer:
Step-by-step explanation:
To add efficiently, you would need to have a common denominator. in this case the least common denominator (LCD) would be 35. 1/7 = 5/35 and 2/5 = 14/35
add the numerators together to get your answer:
19/35
Answer:
There are 5 pigs on Aaron's farm
Step-by-step explanation:
1. Start with 40 animals
2. 1/10 of the animals are cows, so divide 40 by 10 and you will find that 4 of the animals are cows
3. 2/5 of the animals are chickens, so multiple 40 by 2 to get 80 and then divide 80 by 5 and you will find that 16 of the animals are chickens
4. Subtract the 4 cows and 16 chickens from the 40 total animals and you find there are 20 more animals that are neither cows nor chickens
5. Of the 20 remaining animals, 1/4 are pigs, so divide 20 by 4 and you will find that there are 5 pigs
Answer:
let w = the width of the rectangle
let w- 9=the length of the rectangle
A= L×W
220=w(w-9)
220=w^-9w
w^-9w-220=0
(w-20)(w+11)=0
w-20=0 or w+11=0
w=20cm or x-11 illogical answer
Answer:
Step-by-step explanation:
