Answer:

90/13, 45/13

Step-by-step explanation:

$- 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\$

Simplify:

$- 2 \times 9 = - 18 \\ 7 \times ( - 18) + 9 \times 9 = - 45 \\ - 18 = - 18 \\ - 45 = - 45$

If a = 5, b = 5 and c = 10, what is the value of ac / 2b ?

Sophie [7]

Answer:

The answer is 5 .

Step-by-step explanation:

You have to substitute the values of a, b and c into the expression :

$\frac{ac}{2b}$

Let a = 5,

Let b = 5,

Let c = 10,

$\frac{5 \times 10}{2 \times 5}$

$= \frac{50}{10}$

$= 5$
