2/3 and 1/5 is 13/15
you find the GCF (greatest common factor) and then multiply to get the GCF
in this case the GCF is 15 (remember that what you do to the bttom you do to the top
2x5=10-----3x5=15 10/15
1x3=3-------5x3=15 3/15
10/15 + 3/15=13/15

For what value of k does the equation 4+3x=(k+2)x+8

Elena L [17]

4+3x = (k+2)x + 8
4+2+3x = (k+2)x + 8 - 2
6+3x = (k+2)x + 6
then 3x = k+2
so k = 3X-2

Alisha has a $15,000 car loan with a 6 percent interest rate that is compounded annually. How much will she have paid at the end

Citrus2011 [14]

Use the attached formula.
r = 6 / 1,200 = .005
Principal = 15,000
n = number of payments = 5 yrs * 12 months = 60
TOTAL Loan Cost = (.005 * 15,000 * 60) / 1 -(1.005^-60)
TOTAL Loan Cost = 4,500 / (1 - 0.7413721962)
TOTAL Loan Cost = 4,500 / 0.2586278038 
TOTAL Loan Cost = 17,399.52
Although it is NOT one of the choices, I think my answer of 17,399.52 is correct. Using a monthly loan payment calculator, I get 289.99 for the monthly payment. 290*60 months = 17,400 so that seems correct.
I do not think that formula you posted is correct. (Compare it to the one I posted.)

Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long. Maria has 3 4 foot of trim left. Wh

Sergio039 [100]

We have been given that Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long.

The amount of trim will be equal to perimeter of triangle. The perimeter of given triangle will be 3 times each side length that is $3\times 21=63$ inches.

Now we need to convert 63 inches into feet.

12 inches = 1 feet

63 inches = $\frac{63}{12}$ feet = 5.25 feet.

We are also told that Maria has $\frac{3}{4}$ foot of trim left, so total length of trim would be trim used plus trim left that is $5.25+\frac{3}{4}=5.25+0.75=6$ feet.

Since we need to find length of trim in yards, so we will convert 6 feet into yards.

3 feet = 1 yard

6 feet = $\frac{6}{3}$ yards = 2 yards

Therefore, the length of the trim was 2 yards.
