Multiply her monthly payment by the number of months she paid so far:

567 x 48 = 27,216 paid so far.

Now add the amount she still owes:

27,216 + 1,250 = $28,466 total price.

Jeff has $1.35 in nickles and dimes. He has a total of 15 coins. How many of each coin does he have?

dlinn [17]

For this case we propose a system of equations.

We know that a dime equals 10 cents and a nickel equals 5 cents.

So:

x: Let the variable that represents the number of dimes

y: Let the variable that represents the number of nickels

According to the statement we have:

$x + y = 15\\0.10x + 0.05y = 1.35$

We multiply the first equation by -0.10:

$-0.10x-0.10y = -1.5$

We have the following equivalent system:

$0.10x + 0.05y = 1.35\\-0.10x-0.10y = -1.5$

We add the equations:

$0.10x-0.10x + 0.05y-0.10y = 1.35-1.5\\-0.05y = -0.15\\y = \frac {-0.15} {- 0.05}\\y = 3$

So, Jeff has 3 nickels

$x + y = 15\\x + 3 = 15\\x = 15-3\\x = 12$

Jeff has 12 dimes.

Answer:

12 dimes and 3 nickels

Fully Factor 3x^2 – 16x + 20

ryzh [129]

Answer:

C. (3x2 - 10) (x - 2)

Step-by-step explanation:

3x^2 - 16x +20

Step 1: Sum = - 16x

Product = 60x^2

Step 2: Find 2 numbers that their sum is -16 and their product is 60. If you do that correctly, then you will get two numbers: 10 and -6

Step 3: Replace -16x with the two numbers found in step 2, then you will have; 3x^2 - 6x - 10x + 20

Step 4: Factorise the equation in step 3, like so;

(3x^2 - 6x)(- 10x + 20)

3x(x - 2) -10(x - 2)

(3x - 10)(x - 2)

To check if the answer is correct, expand the bracket: (3x - 10)(x - 2)

If the bracket is opened properly, you will get 3x^2 - 16x + 20

A gallon of gasoline cost 2.96. Your car has a 25 gallon gas tank and can travel 28.8 miles on each gallon of gasoline. How much

geniusboy [140]

<h2>Greetings!</h2>

Answer:

It would cost 47.36

Step-by-step explanation:

First, you need to find out how many gallons are needed to fill the tank. To do this, simply multiply 25 by the fraction that is how much is already in there:

25 x $\frac{3}{8}$ = 9.375

So that means that there is 9.375 gallons already in the tank. To find the amount needed to fill the tank:

25 - 9.375 = 15.625

So 15.625 gallons are needed, rounded up to 16 gallons because you cannot get a decimal value of gallons.

That means that 16 x the price = the amount to fill the tank:

16 x 2.96 = 47.36

So it would cost 47.36 to fill the tank!
