PSYCHO15rus [73]

Answer:

Statements: Reasons:

1) ∠2 and ∠4 are vertical angles given

2) limes m and n intersect at P definition of vertical angles

3) ∠3 and ∠4 are linear pair definition of linear pair

4) ∠2 and ∠3 are linear pair definition of linear pair

5) m∠3 + m∠4 =180 angle addition postulate

6) m∠2 + m∠3 =180 angle addition postulate

7) m∠2 + m∠3 = m∠3 + m∠4 substitution property

8) m∠2 = m∠4 subtraction property

9) ∠2 ≅ ∠4 definition of congruent(≅) angles

A box holding pennies, nickels and dimes contains thirteen coins with a total value of 83 cents. How many coins of each type are

Art [367]

Answer:

The number of pennies,nickels and dimes are (p,n,d)=(3,4,6).

Further explanation:

Given:

A box holding pennies, nickels and dimes contains thirteen coins in a box.

Total value is 83 cents.

Calculation:

Consider p,n and d be the number of pennies, nickel and dimes.

Now, total is 13 coins so $p+n+d=13$

As we know that these following are US coin.

Penny=1 cent

Nickel=5 cents

Dime=10 cents

Step 1:

The value is already given as 83 cents that is 80+3 cents.

80 cents can be possible in many combinations as follows:

(N,D)=(0,8),(2,7),(4,6),(6,5),(8,4),(10,3),(12,2),(14,1),(16,0)

It is given that the total number of cents is 13 so we choose (4,6) as (n,d) .

So the value of nickel n=4

Dimes d=6

Step 2:

The value of p is calculated as follows:

Substitute 4 for n, 6 for d in equation $p+n+d=13$ as follows:

$p+4+6=13$

$p+10=13$

$p=13-10$

p=3

Thus, the number of pennies,nickels and dimes are (p,n,d)=(3,4,6).
