You have a coin collection of nickels and dimes containing 63 coins. If you have
$5.05, how may of each coin do you have?

Answers

Answer: 25 nickels

Step-by-step explanation:

EQUATIONS:

quantity: n + d = 63

value: 5n + 10d = 505

-------------------------

Divide thru the 2nd equation by 5 to get:

n + 2d = 101

----------------

Subtract that from the 1st equation:

-d = -38

d = 38 (# of dimes)

---------------

Substitute that into n+d=63 to solve for "n":

n + 38 = 63

n = 25 (# of nickels)

y ≤ x-2


Answer choices:
(0,0)
(0,-1)
(1,1)

Answers

Answer:

(3,0)

Step-by-step explanation:

We want to select an ordered pair that makes the inequality true

From the first one;

y > 1

Thus, the first three sets are wrong as the first two is less than 1 and the 3rd is same as 1

So

the correct answer choice is (3,0)

Answer:

Each side is 1/13 miles long

Step-by-step explanation:

The area of a square is A=s^2 where s is the side length of the square. Remember that a square has all of its sides equal in length to each other. So since we already have the area which is A=1/169mi^2, then we just take the square root of it to get s=1/13. So each side will be 1/13 miles long

Determine the intercepts of the line.

Answers

Answer:

0.43

Step-by-step explanation:

let b be the battery cost

then the torch costs 11b

Tim pays 11b+b = 12b

Since he gets 4.84 change from 10,- we can say:

12b = 10 - 4.84

12b = 5.16

b = 5.16/12 = 0.43

so torch: 4.73

battery: 0.43

total: 5.16

The correct answer will be 0.43 because you are trying to find the different equation to that math problem
