Answer 1

Answer:

B) Jacob has four more nickels than dimes in his pocket, for a total of $1.25. What is x, the number of dimes in his pocket?  

Step-by-step explanation:

The equation is multiplying the number of dimes (x) by the value of a dime 0.10. it is also adding 4 to the value of x ( 4 more nickels than dimes) and multiplying that by the value of a nickel.

Answer 2

Answer:

Given equation : $0.05(x + 4) + 0.10(x) = 1.25$

1 dime = $0.10

1 nickel = $0.05

So, x is the no. of dimes in equation and x+4 is the number of nickels

So, Option B is true  Jacob has four more nickels than dimes in his pocket, for a total of $1.25.

$0.05(x + 4) + 0.10(x) = 1.25$

$0.05x +0.2 + 0.10x = 1.25$

$0.15x +0.2= 1.25$

$0.15x = 1.25-0.2$

$0.15x = 1.05$

$x = \frac{1.05}{0.15}$

$x =7$

Hence  the number of dimes in his pocket is 7
