rearrange into quadratic form ax^2+bx+c=0. . 0.20= x^2/(25-x). . where a=1, and identify values of b and c
vivado [14]
Simplifying 0.20 = x^2 / (25 - x):

Multiply both sides by (25 - x)
0.20(25 - x) = x^2

Distributing 0.20:
5 - 0.20x = x^2

Placing all equations on to one side:
x^2 + 0.20x - 5 = 0

Where:
a = 1
b = 0.20
c = -5

Elsie pays $8.99 for a one-pound canister of Georgia pecans. Write and solve a proportion to determine the cost of 4
ch4aika [34]

Answer:

$ 35.96

Step-by-step explanation:

Let x be the cost ( in dollars ) of 4 ounces of the pecans,

So, the ratio of the cost and ounces needed = \frac{x}{4}

Also, the cost of 1 ounces of pecans is $ 8.99,

Thus, the ratio of the cost and ounces needed = \frac{8.99}{1}

Hence, we can write,

\frac{x}{4}=\frac{8.99}{1}

Which is the required proportion,

By cross multiplication,

x = 4 × 8.99 = 35.96

Therefore, $ 35.96 is the cost of 4 ounces of the pecans.
