Can someone please explain how to solve 3x+3=x-1 will give brainiest :)

1 answer:

6 0

3x+3 = x-1
2x+3 = -1 (subtracted x from both sides)
2x = -4 (subtracted 3 from both sides)
x = -2 (divided 2 from both sides).

Braden bought a piece of commercial real estate for $101,234. The value of the real estate appreciated at a constant rate per ye

MrMuchimi

Answer:

f(t) = 101,234 $(1.03)^{t}$

Step-by-step explanation:

First, use FV formula to find the rate ;r given PV=101,234 and FV=104,271.02 and time= 1 year

$FV= PV (1+r)^{t}$

104,271.02 = 101,234 $(1+r)^{1}$

Divide both sides by 101,234 to get;

104,271.02 / 101,234 = 1+r

1.03 = 1+r

1.03 -1 =r

therefore r= 0.03 or 3%

Next, to get the function of FV of estate after t years; f(t) ;

Plug in the 3% rate found above into the FV formula with PV being the current value of 101,234 and it becomes;

f(t) = 101,234 $(1.03)^{t}$

Nolan is deciding between two truck rental companies. Company A charges an initialfee of $90 for the rental plus $2 per mile dri

kotegsom [21]

first we writte the information they are giving to us:

For company A:

initial fee = $90

rent per mile = $2

For combany B:

initial fee = $50

rent per mile = $3

Now for company A the equation that represent the charge in one mile will be: (where n is the number of miles)

$\begin{gathered} A=90+2(n) \\ A=90+2(1) \\ A=90 \end{gathered}$

And for company B:

$\begin{gathered} B=50+3n \\ B=50+3(1) \\ B=53 \end{gathered}$

Now to determine the number miles driven, that would make the cost of each company the same, we have to make A = B

$\begin{gathered} A=B \\ 90+2n=50+3n \\ \end{gathered}$

and finaly we can solve for n

$\begin{gathered} 90-50=3n-2n \\ 40=n \end{gathered}$

so if they drive for 40 miles the will pay the same
