First, distribute 3 through the parentheses, move variable to the left side and change it’s sign, then move the constant to the right side and change the sign, then combine like terms, add 4+6, divide both sides by 2, then you get x = 5

Answer:

A - 5
B - 4
C - 1
D - 3
E - 2

Step-by-step explanation:

Step 1 is the given expression.

In Step 2, we have used the distributive property to eliminate parentheses.

In Step 3, -x as been added to both sides.

In Step 4, +6 has been added to both sides.

In Step 5, both sides have been multiplied by 1/2.

If the boxes on the left are identified as A to E from top to bottom, they are filled with the numbers 5, 4, 1, 3, 2 in that order.

Brody sliced a small pizza into 12 equal pieces. He ate ~ of the pizza. Which model represents three-fourths of twelve?

EastWind [94]

Answer:

Pie chart.

9 slices

Step-by-step explanation:

Three-fourths of twelve is written as

3/4 * 12

i.e 3/4 is multiplied by 12

multiplying 3 by 12 gives 36 and dividing it by 4 gives 9 .

So Brody ate 9 slices out of the 12 slices of pizza.

The graph used in circular shape is called the a pie chart.

If we draw a pie chart 3 of the 4 sections will be colored showing that he ate 3/4 of the pizza representing 9 slices out of 12.

Each slice can be represented separately.

Use natural logarithms to solve the equation.round to the nearest thousandth 6e^4x-2=3

Vesna [10]

Answer:

x = 0.598

Step-by-step explanation:

$6e^{4x-2} = 3$

Taking natural log on both sides

$ln(6e^{4x-2}) = ln(3)$

(4x-2) ln(6e) = ln(3)

(4x-2) (ln(6) + ln(e)) = ln3 //ln(e) = 1

(4x-2) (ln(6) + 1) = ln3

$4x-2=\frac{ln3}{(ln6+1)}\\\\4x=\frac{ln3}{(ln6+1)} + 2\\\\x = \frac{\frac{ln3}{(ln6+1)} + 2}{4}$

$x = \frac{\frac{ln3}{(ln6+1)} + 2}{4} \\\\x = 0.598$
