Answer:
There are 25 chickens and 20 rabbits
Step-by-step explanation:
Let
x-----> the number of chickens
y ----> the number of rabbits
Remember that
1 chicken has two legs
1 rabbit has four legs
so
2x+4y=130 -------> equation A
x=y+5 -----> equation B
Substitute equation B in equation A and solve for y
2(y+5)+4y=130
2y+10+4y=130
6y=120
y=20 rabbits
Find the value of x
x=y+5
x=20+5=25 chickens
Answer:
35-5a-3a-12-4=-8a+19
4a-12+7=4a-5

Step-by-step explanation: 648
I think its 1.25ft but i could be wrong... sorry if im wrong
Replace each occurrence of x by 7. So we have:-
7^2 + 3 / 7 - 9
= 52 / -2
= -26 answer
