There are 4 pennies. I got this by doing:
40-16=24
16 dimes so far
24/2=12
16 dimes, 12 quarters
16+12=28    40-28=12
12 coins left
Then I drew a diagram and for every 1 penny I drew 2 nickels. In order to get 12 overall in pennies and nickels there has to be 8 nickels and 4 pennies.
 Hope that helped! :)

Answer:

\triangle BOT \cong \triangle IEW

Step-by-step explanation:

We are given the following in the question:

\angle BTO \cong \angle IWE\\WI \cong BT\\OT \cong EW

We have to prove:

\triangle BOT \cong \triangle IEW

Proof:

\text{In }\triangle BOT \text{ and } \triangle IEW

we can write:

\angle BTO = \angle IWE\text{ (Given)}\\WI \cong BT\text{ (Given)}\\OT \cong EW\text{ (Given)}

Hence, the two triangle are congruent by SAS congruency rule.

\triangle BOT \cong \triangle IEW

The attached image shows the two triangle.

Why would someone choose to use a graphing calculator to solve a system of linear equations instead of graphing by hand? Explain
11Alexandr11 [23.1K]
A graphing calculator is just easier to graph the points than having to put every point on a piece of graph paper. the calculator also can tell you a bunch of other things like the domain or range or y intercept or x intercept. it’s just all along easier

Which shows the correct method for solving the equation below?<br> 1/3 (y-9) =3
lyudmila [28]

Answer:

y=18

Step-by-step explanation:

we have

\frac{1}{3}(y-9)=3

Multiply by 3 both sides

3*(\frac{1}{3}(y-9))=3*3

(y-9)=9

Adds 9 both sides

(y-9)+9=9+9

y=18
