Nicholas has 22 nickels, dimes, and quarters. There are 3
less dimes than quarters and 2 more dimes than nickels.
How much money does he have?

Answers

Nickels: 22

Dimes: 24

Quarters: 27

2 more dimes than nickels, we already know that there are 22 nickles so...

Dimes= 24

3 less dimes that quarters ^(we already know how many dimes).

All we have to do is add 3 to the amount of dimes!

Quarters 27

____________________________________________________________

Now to find the amount of money you have to find out what each coin equals and multiply the number of coins by the cost of each coin, and then by 100 because there are 100 cents in 1 dollar.

22 nickels*5/100= $1.10

24 dimes*10/100= $2.40

27 quarters*25/100= $6.75

1.10+2.40+6.75= $10.25

The amount of money he has in $10.25

The domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

0 ≤ y ≤ 72

The range will be y ∈ [0, 72]

0 ≤ x ≤ 72

The domain will be x ∈ [0, 72]

0 ≤ x ≤ 6

The domain will be x ∈ [0, 1, 2, 3, 4, 5, 6]

0 ≤ y ≤ 6

The range will be y ∈ [0, 1, 2, 3, 4, 5, 6]

Thus, the domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].

If the sides to a triangle are 20, 40, and 80 cem, is it Right triangle?

Answers

Answer: no

because using Pytago theorem, we have:

20² + 40² ≠ 80²

80² + 20² ≠ 40²

80² + 40 ² ≠ 20²

Step-by-step explanation:

Answer:

No, it does not follow the Pythagorean Theorem.

Step-by-step explanation:

A right triangle must follow the equation a^2 + b^2 = c^2 for its sides to be true. 20^2 + 40^2 = 2000.

the square root of 2000 equals about 44.7213595.

Thus, a triangle with sides 20, 40, and 80 is not a right triangle.

4x – 2y = 2
x = y + 4

Answers

Answer:

y = -7 and x = -3

Step-by-step explanation:

Substitute x for y + 4 in the first equation and solve for y

4(y+4) - 2y = 2

4y + 16 - 2y = 2

16 + 2y = 2

2y = -14

y = -7

Then in order to find x, substitute y for -7 in the second equation

x = -7 + 4

x = -3

Answer:

x= -3, y= -7

Step-by-step explanation:

substitute x=y+4 in the first equation

4 (y+4) -2y =2 distribute

4y+16-2y=2 subtract both sides by 16

4y-2y=2-16 combine like terms

2y= -14 divide both sides by 2

y=-7

x=y+4 substitute y=-7

x= -7+4
