Bob has $1.15 in his wallet which contains 18 coins in nickels and dimes. Find how many nickles he has.

ratelena [41]

9514 1404 393

Answer:

13 nickels

Step-by-step explanation:

Let n represent the number of nickels Bob has. Then 18-n is the number of dimes, and the total value (in cents) is ...

5n +10(18-n) = 115

-5n +180 = 115 . . . simplify

65 = 5n . . . . . add 5n-115

13 = n . . . . . . . divide by 5

Bob has 13 nickels.

Verdadero o falso a) al reducir a comun denominador las fracciones se sustituyen por otras equivalentes

alexgriva [62]

Answer:

Verdadero

Step-by-step explanation:

Verdadero, cuando cambias dos fracciones para darles un denominador comun la fraccion entera se sustituye para otra que tiene el mismo valor numerico que la original. Por ejemplo tenemos una fraccion 2/6 en la cual tenemos que cambiarle el denominador a uno comun con otra fraccion que es 18. Entonces sustituyemos la fraccion por la siguente fraccion 6/18. Esta nueva fraccion es equivalente a la original y los dos tienen el mismo valor numerico...

2 / 6 = 0.333

6 / 18 = 0.333

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point A(3, 8)

Point B(-1, 1)

Step 2: Find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1 - 3)^2 + (1 - 8)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-4)^2 + (-7)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{16 + 49}$
[√Radical] Add: $\displaystyle d = \sqrt{65}$
