Answer: There are 99 three-legged-cows and 28 chickens.
Step-by-step explanation:
Let x be the number of three-legged-cows and y be the number of chickens.
Number of legs in chicken = 2
The according to the question, we have the following equations :-
Multiplying 2 to the equation (1), we get
Now, subtract equation (3) from (2), we get
Put x= 99 in (1), we get
Hence, there are 99 three-legged-cows and 28 chickens.
Simplify each term<span>.
</span><span>10x−20−11=4+3x
</span>Add <span>−20</span><span> and </span><span>−11</span><span> to get </span><span><span>−31</span>.
</span><span>10x−31=4+3x
</span>Move 3x to the left-hand side of the equation<span> by subtracting </span><span>3x</span><span> from both sides.
</span><span>10x−31−3x=4
</span>Add <span>10x</span><span> and </span><span>−3x</span><span> to get </span><span><span>7x</span>.
</span><span>7x−31=4
</span>Since <span>−31</span><span> does not contain the </span>variable<span> to solve for, move it to the right-hand side of the </span>equation<span> by adding </span>31<span> to both sides.
</span><span>7x=31+4
</span>Add 31<span> and </span>4<span> to get </span><span>35.
</span><span>7x=35
</span>Divide<span> each </span>term<span> in the </span>equation<span> by </span><span>7.
</span><span>x=5</span>
Answer:
Step-by-step explanation:
So, yearly $2100 is paid, plus the 1.73% interest, so 1.73% interest is $2136.33every year interest stacks on itself so youll take 1.73% of the year 1 total with interest.
Year 1 total: $2136.33
Year 2 total:$2173.29
Year 3 total:$2210.89
Year 4 total:$2249.14
Year 5 total:$2288.05
Total Paid After 5 years:$11057.70
Year 1 total interest:$36.33
Year 2 total interest:$36.96Year 3 total interest:$37.60Year 4 total interest:$38.25Year 5 total interest:$38.91
Total Interest paid after 5 years:$188.05
