Answer:

x= -1.2

Step-by-step explanation:

Simplifying

-7 + 12 + -2x = 23 + 13x

Combine like terms: -7 + 12 = 5

5 + -2x = 23 + 13x

Solving

5 + -2x = 23 + 13x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13x' to each side of the equation.

5 + -2x + -13x = 23 + 13x + -13x

Combine like terms: -2x + -13x = -15x

5 + -15x = 23 + 13x + -13x

Combine like terms: 13x + -13x = 0

5 + -15x = 23 + 0

5 + -15x = 23

Add '-5' to each side of the equation.

5 + -5 + -15x = 23 + -5

Combine like terms: 5 + -5 = 0

0 + -15x = 23 + -5

-15x = 23 + -5

Combine like terms: 23 + -5 = 18

-15x = 18

Divide each side by '-15'.

x = -1.2

Answer:

Therefore, we use the linear depreciation and we get is 17222.22 .

Step-by-step explanation:

From Exercise we have that is boat $250,000.

The straight line depreciation for a boat would be calculated as follows:

Cost boat is $250,000.

For $95,000 Deep Blue plans to sell it after 9 years.

We use the formula and we calculate :

(250000-95000)/9=155000/9=17222.22

Therefore, we use the linear depreciation and we get is 17222.22 .

A student raises her grade average from a 75 to a 90. What was the percent of increase

son4ous [18]

This can be solved algebraically. Before we start, as context, to find a percentage you multiply by the percentage/100.

$75*x=90 \\ x= \frac{90}{75} \\ \\ \boxed{x=1.2}$

This tells us that 90 is 120% of 75. However, your question wants us to find the <em>increase</em>, therefore we don't need that 100.
Therefore, the increase is 20%.
