Mr.Martin states that in order for the solution to the equation 3x + q = 6 to be positive, the value of q must be less than 6. S
Virty [35]

Answer:

Mr. Martin's statement is correct.

Step-by-step explanation:

First we select a value of q that is less than 6:

q = 3

Then we <u>write the equation:</u>

  • 3x + 3 = 6

And <u>solve for x</u>:

  • 3x = 6 - 4
  • 3x = 3
  • x =  3/3
  • x = 1

The solution is positive because x > 0.

--

Then we select a value of q that is not less than 6:

q = 9

Then we <u>write the equation:</u>

  • 3x + 9 = 6

And <u>solve for x</u>:

  • 3x = 6 - 9
  • 3x = -3
  • x =  -3/3
  • x = -1

The solution is negative because x > 0.

Elis [28]

Answer:$11848.64

Step-by-step explanation:

Let P be the principal.

Let A be the amount after t years.

Let t be the time period.

Let i be interest rate.

Given,

P=5428\\i=5\%\\t=16

A=P(1+\dfrac{i}{100})^{t}

A=5428\times (1+\frac{5}{100})^{16}=5428\times (1.05)^{16}=5428\times 2.182=11848.64
