Justin car can travel 75 miles using 3 gallons of gas. At this rate, how far, in miles, can Justin travel using 8 gallons of gas

AlekseyPX

Answer:

Justin travels 211.83 miles on 8.2 gallons of gas.

Step-by-step explanation:

77.5 miles / 3.1 gallons = x miles / 8.2 gallons

Solve for x... multiply by 8.2 gallons on both sides (that cancels it on the right) side of the equation.

8.2 gallons *77.5 miles / 3.1 gallons = x

635.5/ 3.1 = x

211.83 miles = x

How many solutions are there in -2x+3y=7 and 2x-3y=-7

Rainbow [258]

The system has Infinitely many solutions.

Step-by-step explanation:

We need to find how many solutions are there in:

$-2x+3y=7\\ 2x-3y=-7$

Let:

$-2x+3y=7\,\,\,eq(1)\\ 2x-3y=-7\,\,\,eq(2)$

Adding eq(1) and eq(2)

$-2x+3y=7\\ 2x-3y=-7\\-------\\0=0$

Since a constant term is equal to constant term, so the system has Infinitely many solutions.

How much would $200 invested at 6% interest compounded annually be worth after 6 years? Round your answer to the nearest cent.

Neko [114]

$A=P(1+ \frac{r}{n})^{nt}$
A=future amount
P=present amount
r=rate in decimal form
n=number of times per year to be compounded
t=time in years

so
P=200
r=0.06
n=1
t=6

evaluate to find A
$A=200(1+ \frac{0.06}{1})^{(1)(6)}$
$A=200P(1.06)^{6}$
A=283.704
round
A=$283.70
