Answer:
R17.98
Step-by-step explanation:
Required in the recipe = 250 g Fat free cottage cheese ;
125 g Fat free cottage cheese = R8.99
For 250g Fat free cottage cheese ; 250 / 125 = 2 125 g fat free cottage cheese is required ;
1 125 g Fat free cheese =. R8. 99
2 125g fat free cottage cheese =. R8. 99 * 2
R8. 99 * 2 = R17.98
you could either multiply straight away or you could simplify right then so that you wouldn't have to it later.
20/5 * 5/2
your answer would be 10 either way

The standard form of linear equations is Ax + By = C where A and B ≠ 0, and A is non-negative.
Therefore, the correct answer is A) 6x - 7y = 8
Answer:
f(n) = 2n - 2
Step-by-step explanation:
Given the recursive formula
f(n) = f(n - 1) + 2 with f(1) = 0, then
f(2) = f(1) + 2 = 0 + 2 = 2
f(3) = f(2) + 2 = 2 + 2 = 4
f(4) = f(3) + 2 = 4 + 2 = 6
The terms of the sequence are 0, 2, 4, 6, ....
These are the first 4 terms of an arithmetic sequence with explicit formula
f(n) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here d = 2 - 0 = 4 - 2 = 6 - 4 = 2 and a₁ = 0, thus
f(n) = 0 + 2(n - 1), that is
f(n) = 2n - 2 ← explicit formula
