The solution would be like this
for this specific problem:
8479 = P * (1 + 0.09/2)^(2 * 6) <span>
8479 = P * (1 + 0.045)^12
8479 / (1.045)^12 = P
P = 4999.7599101968641899706115543368</span>

Answer:
n = -1
Step-by-step explanation:
n - 2 = 1/2 (10n+4) // We have the equation.
n - 2 = 5n + 2 // Solve the righ side.
n - 5n = 2 + 2 // Group common terms.
-4n = 4 // Solve.
n = -4/4
n = -1
From the number 842 to 109 is a decrease of 733. so 109 minus 733 will result in a -624.
Answer:
Reduced fraction: 58. Therefore, 35/56 simplified to lowest terms is 5/8
Question:
The quantities x and y are proportional.
x y
5.8 7.5

Find the constant of proportionality (r) in the equation y=rx
Answer:
The constant of proportionality is 75/58 or 1.29
Step-by-step explanation:
Given
The table above
Required
Find the constant of proportionality
The question has an incomplete table but it can still be solved because x and y are proportional.
Given that
y = rx
Make r the subject of formula
Divide through by x
y/x = rx
y/x = r
r = y/x
When y = 7.5, x = 5.8
Substitute these values
r = y/x becomes
r = 7.5/5.8
Multiply denominator and numerator by 10
r = (7.5 * 10)/(5.8 * 10)
r = 75/58
In this case, it's best to leave the answer in fraction.
However, it can be solved further.
r = 75/58
r = 1.29 (Approximated)
Hence, the constant of proportionality is 75/58 or 1.29
