Angles on a straight line always adds up to 180°

The angle on the left side of 100° is, (180-100) = 80

Do the same with 80° and the angle beneath it (Remember! angles add up to 180° on a straight line).

Hence, 180 - (x+105) = 80
=> 180-80 = x+105
=> 100-105 = x
x = -5

Given : A customer is owed $30.00.

To find : How many different combinations of bills,using only five, ten, and twenty dollars bills are possible to give his or her change?

Solution :

We have to split $30 in terms of only five, ten, and twenty dollars.

1) In terms of only five we required 6 fives as

$6\times 5=30$

So, 6 fives.

2) In terms of only ten and five,

a) We required 1 ten and 4 fives as

$1\times 10+4\times 5=10+20=30$

So, 1 ten and 4 fives.

b) We required 2 tens and 2 fives as

$2\times 10+2\times 5=20+10=30$

So, 2 tens and 2 fives

3) In terms of only tens we require 3 tens as

$3\times 10=30$

So, 3 tens.

4) In terms of only twenty and five, we required 1 twenty and 2 fives as

$1\times 20+2\times 5=20+10=30$

So, 1 twenty and 2 fives.

5) In terms of only twenty and ten, we required 1 twenty and 1 ten as

$1\times 20+1\times 10=20+10=30$

So, 1 twenty and 1 ten.

Therefore, There are 6 different combinations.

Answer:

5n + 10d represented the money spend by the Amy in playing board games of cost $5 and $10 .

Step-by-step explanation:

As given

Amy and Mary are playing a board game that uses game money if $5 and $10.

At the end of the game, Amy has n bills worth $5 each and d bills worth $10 each .

Total amount of n bills = 5n

Total amount of d bills = 10d

Thus

Total money spend by the Amy in playing board games = Total amount of n bills + Total amount of d bills

= 5n + 10d

Therefore 5n + 10d represented the money spend by the Amy in playing board games of cost $5 and $10 .
