What is A and B if A+B is 7/12 and A-B is 5/12?

1 answer:

7 0

A would be 6/12 (1/2) and B would be 1/12. To make this easier to understand, think of it this way. 6+1=7, and 6-1=5. In the future, find what adds to 7 and begin plugging in numbers until you get the correct answer.

Answer:

$Blue = \frac{8}{9}$

Step-by-step explanation:

Given

$Yellow = 1ft^2$

$Blue = 8z^{-1$

Required

Evaluate Blue when z = 9

To do this, we simply substitute 9 for z in $Blue = 8z^{-1$

$Blue = 8 * 9^{-1$

Convert indices to fraction

$Blue = 8 * \frac{1}{9}$

$Blue = \frac{8}{9}$

<em>Hence, the blue section has an area of </em> $\frac{8}{9}ft^2$ <em></em>
