i have 17 coins. N of them are nickels and the rest are dimes. write an expression in two different ways for the amount of money
sergiy2304 [10]

Answer:

0.05N - 0.1N + 1.7 (in dollars

1.7 - 0.05N (in dollars)

Step-by-step explanation:

Given :

Total number of coins = 17

Number of nickels = N

Number of dimes = 17 - N

1 nickel = 5 cent = $0.05

1 dime = 10 cent = $0.1

The amount of money :

(Value of nickel * number of nickels) + (value of dime * number of dime)

(0.05 * N) + (0.1 * (17-N))

0.05N + 1.7 - 0.1N

0.05N - 0.1N + 1.7

-0.05N + 1.7 = 1.7 - 0.05N

Please answer one question asap <br>A(-4,3) B(2,-1) D(-4,-1) C(2,-5)
Leni [432]

Answer:

Step-by-step explanation:

Vertices of the given quadrilateral are A(-4, 3), B(2, -1), C(2, -5) and D(-4, -1)

Since, slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

Slope of AB = \frac{3+1}{-4-2}

                    = -\frac{2}{3}

Slope of AD = \frac{3+1}{-4+4}

                    = Not defined (Parallel to y-axis)

Slope of DC = \frac{-5+1}{2+4}

                     = -\frac{2}{3}

Slope of BC = \frac{-1+5}{2-2}

                   = Not defined (Parallel to y-axis)

Slope of AB = slope of DC = -\frac{2}{3}

Slope of BC = slope of AD = Not defined (parallel to y-axis)

As per property of a parallelogram,

"Opposite sides of a parallelogram are parallel and equal in measure"                  

Therefore, ABCD is a parallelogram.
