Answer:
In Nelson Mandela's family he was the first to receive a formal education. At that time, very few black kids attained high school education in South Africa.
Algebraically, that will be expressed as:
The interest is compounded quarterly because the formula is
A=p (1+r/k)^kt
A it's 18810.67 but I will assume it's unknown ?
P present value 7350
R interest rate 0.045
K compounded quarterly 4
Now solve the formula as the interest is compoundedquarterly
A=7,350×(1+0.045÷4)^(4×21)
A=18,810.67
So the answer is quarterly
the formula for perimeter is l+l+w+w
So 9+9+6+6= 30 meters of fence
To solve this system, we can use substitution.
x + 6y = 61
x = 61 - 6y
Now we substitute into the other equation.
4 (61 - 6y) - 5y = -17
244 - 24y - 5y = -17
244 -29y = -17
29y = 261
y = 9
Now we find x.
x + 6 (9) = 61
x + 54 = 61
x = 7
That means the solution to this system is (7, 9)
