Answer 1

Answer:

$a=250, \ b=10$

Step-by-step explanation:

$a=\frac{5\cdot10^2}2=\frac{5\cdot100}2=\frac{500}2=250\\ b=\frac{2\cdot10^2\cdot(10-5)}{10\cdot10}=\frac{2\cdot100\cdot5}{100}=\frac{1000}{100}=10$

Answer 2

Hi there!

Find the value of a and b when x = 10.

-------------------------------------------------------

Let's solve A:

$a = \frac{5(10)^2}{2}$

$a = \frac{5 * 100}{2}$

$a = \frac{500}{2}$

$a = 250$

-------------------------------------------------------

Let's solve B:

$b = \frac{2(10)^2(x(10)-5)}{10(10)}$

$b = \frac{2(100)(5)}{100}$

$b = \frac{200 * 5}{100}$

$b = \frac{1000}{100}$

$b = 10$
