olga nikolaevna [1]

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>

there are 27 red or blue marbles in the bag the number of red marbles is 5 less than three times the number of blue marbles how
maria [59]
Answer=24 blue marbles and 3 red marbles

r=red marbles
b=blue marbles
b=3(r+5)

27=b+r
substitue b for '3(r+5)'
27=3(r+5)+r
27=3r+15+r
27=4r+15
subtract 15 from both sides
12=4r
divide both sides by 4
3=r

There are 3 red marbles

27=b+r
27=b+3
subtract 3 from both sides
24=b

There are 24 blue marbles
