Looking at the question, I'm assuming it has a mistake.
However, I will first attempt to solve it normally:
Simply combine like terms to get 5x = 180, and thus x = 36, and y = 72
The first mistake possibility is that the first equation should be <u>3x + 2y = 180</u>
If that is the case, simply substitute in 2x for y, turning the equation into
3x + 2 (2x) = 180
3x + 4x = 180
7x = 180
Thus, x = 25.715 and y = 51.43
Another possible mistake is that the first equation should be <u>3y + 2x</u><u> </u><u>= 180</u>
Solve similar to the first mistake
3 (2x) + 2x = 180
6x + 2x = 180
8x = 180
Thus, x = 22.5, and y = 45
Hope it helps :)
The probability is 2/10 because the only numbers less than 3 from 1-10 is 1 and 2. So it would be 2/10, 20%, or unlikely.
Answer:
1190
Step-by-step explanation:
Here, you need to add the squares of the measurements.
20² + 10² + 13² + 11² + 20² =
= 400 + 100 + 169 + 121 + 400
= 1190
Answer:
No savings
Step-by-step explanation:
Let the interest rate be same for all the loans and consider it to be R.
<u>First case</u>
Principal 1 = 2000
Time = 12 moths =
= 1 year
Rate = R %
So, interest 1 = Principal * Time * Rate
= 2000 * 1 * R
= 2000R
Now,
Principal 2 = 1000
Time = 12 moths =
= 1 year
Rate = R %
So, interest 2 = Principal * Time * Rate
= 1000 * 1 * R
= 1000R
Total interest to be paid = 2000R + 1000R
= 3000R
<u>Second case</u>
Principal = 3000
Time = 12 moths =
= 1 year
Rate = R %
Interest = Principal * Time * Rate
= 3000 * 1 * R
= 3000R
We conclude that there would be no savings because the interest to be paid in both the cases are same.
