Answer:

Samantha is correct because when using x = 2, the resulting values in both expressions are equal.

Step-by-step explanation:

x + 17 + 3x - 15  

x + 3x + 17 - 15 = 4x + 2.

X + 17 +3x -15

x +3x = 4x

17-15 = 2
 which becomes 4x +2 so it is true

Suppose a house costs $270,000 appreciates by 5% each year. In about how many years will the house be worth $350000?
Vikki [24]
350000 =  270000(1.05)^n

1.05)^n = 350000/270000 = 1.296296

n =  log 1.296296 / log 1.05 = 5.3 years answer

Can anyone help me with this. It asks to solve and check your answer.
tankabanditka [31]
\sf 4m-21=3(5m-1)

First, distribute 3 into the parenthesis(multiply it to every term inside):

\sf 4m-21=15m-3

Add 21 to both sides:

\sf 4m=15m+18

Subtract 15m to both sides:

\sf -11m=18

Divide -11 to both sides:

\sf m=-\dfrac{18}{11}

To check our work we can plug this back into the original equation for 'm':

\sf 4m-21=3(5m-1)

\sf 4(-\dfrac{18}{11})-21=3(5(-\dfrac{18}{11})-1)

Multiply:

\sf -\dfrac{72}{11}-21=3(-\dfrac{90}{11}-1)

Distribute 3 into the parenthesis:

\sf -\dfrac{72}{11}-21=-\dfrac{270}{11}-3

Subtract:

\sf -\dfrac{303}{11}=-\dfrac{303}{11}~\checkmark

Both sides are equal to each other, so we solved it correctly.
