Let assume that the the two numbers are X and Y and that X is the large number.
According to the question,
X + Y = 53 .................. Equation 1
then, X = 11 + Y........... Equation 2
Substitute equation 2 into equation 1.
[11 + Y] + Y = 53
11 + 2Y = 53
2Y = 53 - 11 = 42
2Y = 42
Y = 42 / 2 = 21,
Therefore, Y = 21 [Small number].
According to equation 1,
X +Y = 53
X + 21 = 53
X = 53 - 21 = 32.
Therefore, X = 32 [Big number].

The value of r(x) at f(- 6) = 8.
We have the function r(x) =
We have to find the value of r(x) at x = - 6.
<h3>If f(x) = 5x + 3, then find the value of f(-2).</h3>
Substitute x = - 2 in the value of f(x) -
f(-2) = 5 (-2) + 3 = - 10 + 3 = - 7.
According to question, we have -
f(x) =
Substitute r = -6 in f(x), we have -
f(-6) =
f(-6) = - 2 x - 2 + 4
f(-6) = 4 + 4 = 8
Hence, the value of f(x) at f(- 6) = 8.

Answer:
Yes
Step-by-step explanation:
<h3><u>Given</u>:</h3>
A cycle is marked at ₹4500 and sold for rupees ₹4185.
Now, To find discount
4500 × 7 ÷ 100 = ₹315
Now,
4500 - 315 = ₹4185
Thus, The answer is Yes Agreed!

Answer:
A) 4.77%.
B) 5%.
Step-by-step explanation:
Given that Adam borrows $ 6,000 from his parents today for university fees and he promises to pay a lump sum of $ 6,900 in 3 years' time, to calculate the effective annual interest rate and the equivalent simple annual interest rate the following calculations must be performed:
A)
6,900 = 6,000 x (1 + X / 1) ^ 3x1
6,900 = 6,000 x 1X ^ 3
6,900 = 6,000 x 1 x 4.77 ^ 3
Thus, the interest rate of said investment is 4.77% per year.
B)
(6,900 - 6,000) / 3 = 300
6,000 = 100
300 = X
300 x 100 / 6,000 = X
30000 / 6,000 = X
5 = X
Thus, the simple interest rate would be 5% per year.
