Rhonda has $1.35 in nickels and dimes in her pocket. if she has six more dimes than nickels, which equation can be used to determine x, the number of nickels she has?

a: 0.05+0.10(6x)=1.35
b: 0.05(x+6)+0.10x=1.35
c: 0.05x+0.10(x+6)=1.35
d: 0.15(x+6)=1.35

Option C. 0.05x+0.10(x+6)=1.35

Step-by-step explanation:

Remember that

1 nickel=$0.05

1 dime=$0.10

Let

x> the number of nickels

y> the number of dimes

we know that

0.05x+0.10y=1.35 > equation A

y=x+6 > equation B

substitute equation B in equation A and solve for x

0.05x+0.10(x+6)=1.35

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
