3x - 2 = 13

Add 2 on both sides

3x - 2 + 2 = 13 + 2
3x = 13 + 2
3x = 15

Divide both sides by 3.

3x/3 = 15/3

x = 15/3

x = 5

Your final answer is A. 5.

The value of a boat if depreciating at at a rate of 9% per year. In 2006 the boat was worth $17,800. Find the worth of the boat
svetlana [45]

Answer:

The worth of boat in 2013 will be $9202.6

Step-by-step explanation:

Rate of depreciation = 9% = 0.09

Cost of Boat in 2006 =$ 17,800

Cost of Boat in 2013 = ?

Years = 2013-2006= 7 years

The formula used is: \mathbf{A=P(1+r)^{t}}

Since the value of boat is depreciating the value of r will be r=-0.09

Here P = 17,800 , r=-0.09 and t = 7 years Finding A

A=P(1+r)^{t}\\A=17,800(1+(-0.09))^7\\A=17,800(0.91)^7\\A=17,800(0.517)\\A=9202.6

So, the worth of boat in 2013 will be $9202.6

Look at the equations below. Identify which equation has infinitely many solutions A. 21 + 2.5w = 6 +5.7w - 3.2w + 15 B. 9k +1 =
Volgvan

The equation that has infinitely many solutions in the options is 21 + 2.5w = 6 +5.7w - 3.2w + 15

<h3 /><h3 /><h3>What is an equation with an Infinitely many solution:</h3>

An equation with infinitely many solutions essentially have same thing on both sides.

Generally, a linear equation has infinitely many solution when the equations are equivalent. Let take for example:

  • 2y + 2= y + y + 2

The equation above have infinitely many solution because there is no actual value of y.

Therefore,

2y + 2 = 2y + 2

2 = 2

We can see both sides are equal to each other. So, this is an infinitely many solution.

Therefore, 21 + 2.5w = 6 +5.7w - 3.2w + 15 has an infinitely many solution.

  • 21 + 2.5w = 6 +5.7w - 3.2w + 15
  • 21 + 2.5w  = 6 + 15 + 5.7w - 3.2w
  • 21 + 2.5w = 21 + 2.5w
  • 21 = 21
  • 0 = 0
