If you would like to simplify a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]}, you can do this using the following steps:

a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]} = a - {4b - [a - 5b + c + 3c - a + b + 9c]} = a - {4b - [- 4b + 13c]} = a - {4b + 4b - 13c} = a - {8b - 13c} = a - 8b + 13c

The correct result would be b) a - 8b + 13c.

To simplify a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]} , we group the like terms and perform addition adn subtraction to these grouped terms. no multiplication nor division is applied. In thi case, the grouping results to
a - 4b + a - 5b +c + 3c - a + b + 9c = a -8 b + 13c. answer is B

Use the graph to answer the question. Find the slope

Liula [17]

We can take the two points given and plug them into the slope formula.

$\sf~m=\dfrac{y_2-y_1}{x_2-x_1}$

(-3, 3), (1, -5)
x1 y1 x2 y2

$\sf~m=\dfrac{-5-3}{1-(-3)}$

Subtract:

$\sf~m=\dfrac{-8}{4}$

Divide:

$\sf~m=-2$

Find the radius of a circle whose circumference is 31.4 centimeters. Approximate Π as 3.14.

sladkih [1.3K]

The circumference of every circle is (pi) times (diameter).

The diameter is (2 x radius), so we can write

Circumference = (pi) x (2 x radius) .

The question gives us the circumference, and the number to use for (pi).
I shall now pluggum in:

(31.4 cm) = (3.14) x (2 x radius)

Divide each side by 3.14: (31.4 cm)/(3.14) = 2 x radius

Divide each side by 2 : (31.4 cm) / (2 x 3.14) = radius

5 cm = radius
