6. You have a coin collection of nickels and dimes containing 63 coins. If you have $5.05, how may of each coin
S_A_V [24]

Answer:

n + d = 20....n = 20 - d

0.05n + 0.10d = 1.35

0.05(20 - d) + 0.10n = 1.35

1 - 0.05d + 0.10d = 1.35

-0.05d + 0.10d = 1.35 - 1

0.05d = 0.35

d = 0.35/0.05

d = 7 <==== 7 dimes

n + d = 20

n + 7 = 20

n = 20 - 7

n = 13 <=== 13 nickels

Pls tell me how to do it
Nikolay [14]

Answer:

1) 35

2) 125

Step-by-step explanation:

1)

angle adc = x

x+ 90 + 20 = 180                (triangke sum property)\

x = 180 - 110 = 70

angle bdc = 70/ 2 = 35          ( the median cuts the angle into 2)

2) cbd = x = 125

x + c + bdc = 180

x + 35 + 20 = 180

x = 180 - 55 =  125

I hope im right!!!

The sum of four consecutive numbers is -26. what are the numbers?
True [87]
Answer: -8, -7, -6, -5

Remember: consecutive numbers are numbers that are back to back. For example, 1, 2, 3, and 4 are consecutive numbers while 1, 3, 5, and 6 are not.

Form your equation. Let x be your first number, x + 1 your second number, x + 2 your third, and x + 3 is your fourth. To further understand this, temporarily substitute 1 for x, and you will find that they are consecutive.
(x) + (x + 1) + (x + 2) + (x + 3) = -26

Solve for x.
(x) + (x + 1) + (x + 2) + (x + 3) = -26               Distributive Property
x + x + 1 + x + 2 + x + 3 = -26                      Combine like terms
4x + 1 + 2 + 3 = -26                                     Combine like terms
4x + 6 = -26                                                 Subtract 6 from both sides
4x = -32                                                       Divide by 4 to both sides
x = -8                                                            Isolated x

Substitute (-8) for x to find the numbers.
1st #: x = -8
2nd #: x + 1 = (-8) + 1 = -7
3rd #: x + 2 = (-8) + 2 = -6
4th #: x + 3 = (-8) + 3 = -5

The numbers are -8, -7, -6, and -5.

You can also check your work.
(-8) + (-7) + (-6) + (-5) = -26
-26 = -26

vertical asymptote at x = 2 and x = - 2

horizontal asymptote at y = 2

the function → ±  ∞ at x = 2 and x = - 2 ⇒ vertical asymptotes

As x → ± ∞, y → -2 ⇒ y = -2 is a horizontal asymptote
