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:
m=2y-3

Step-by-step explanation:
A percentage is a way to describe a part of a whole. The money that is raised by Nina in the second month is $960.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the money raised by Nina in the first month is $800, while the money raised by Nina in the second month is 20% more.
Therefore, the money raised by Nina in the second month is,
Money raised = $800 + 20% of $800
= $800 + 0.20($800)
= $800 + $160
= $960
Hence, the money that is raised by Nina in the second month is $960.
