13 units from 20 could either be 33 or 7; 15 units from -8 could either be 7 or 23.Since 7 satisfy both of the above requirements, Sarah's favorite number is 7. (You could show your work using a number line)

The two possibilities of Neil's favorite number are 26 and -12.

SECOND PART:
7+19=26
7-19=-12
Nails favorite number could be 26 or -12 because Nails favorite number could be 19 units before Sasha's or after.

The equasion she would use would be 60,000 = 1000x + 40,000

this would means 1,000 times a number plus the 40,000 shes already getting equals 60,000

In the given triangle we have the following:

A. The sum of the inner angles of a triangle is always equal to 180, that is:

$\angle1+\angle2+\angle3=180$

From this, we can solve for the sum of angles 1 and 2 and we get:

$\angle1+\angle2=180-\angle3$

Now, we also know that angles 3 and 4 are supplementary angles and therefore their sum is 180 degrees, that is:

$\angle4+\angle3=180$

Solving for angle 4:

$\angle4=180-\angle3$

Equating both results we get:

$\angle1+\angle2=\angle4$

Therefore, it is true that angle 4 is the sum of angles 1 and 2.

B. We have that the sum of angles 2 and 3 is:

$\angle2+\angle3=180-\angle1$

If this were equal to angle 4 we would have:

$\begin{gathered} \angle4=180-\angle1 \\ \angle4+\angle1=180 \end{gathered}$

Answer:The number of nickles is 6

The number of dims is 12 .

Step-by-step explanation:

Given as :

Sum of total number of dims and nickels coins = 18

The value of total combination = $1.50

Let The total number of dims = d

Let The total number of nickels = n

1 nickles = $0.05

1 dims = $0.1

According to question

Total number of dims and nickels coins = number of dims + number of nickels

Or, d + n = 18 .........1

And

$0.1 ×d + $0.05 ×n = $1.50

Or, 0.1 d + 0.05 n = 1.50 .........2

Now, Solving eq 1 an eq 2

0.1 × (d + n) - (0.1 d + 0.05 n) = 0.1 × 18 - 1.50

Or, (0.1 d - 0.1 d) + (0.1 n - 0.05 n) = 1.8 - 1.50

Or, 0 + 0.05 n = 0.3

Or, 0.05 n = 0.3

∴ n =

i.e n = 6

So, The number of nickles = n = 6

Put the value of n int eq 1

∵ d + n = 18

Or, d = 18 - n

Or, d = 18 - 6

i.e d = 12

So, The number of dims = d = 12

Hence, The number of nickles is 6 and the number of dims is 12 .
