Layla has $0.80 worth of nickels and dimes. She has 5 more dimes than nickels. By following the steps below, determine the number of nickels, x, x, and the number of dimes, y, y, that Layla has.

Step-by-step explanation:

X = number of nickels

Y= number of dimes

.5x + .10x + 5= .80

.15x +.50 =.80

Subract .5 from both sides and

Divide by .15 on both sides

x= 2 therefore you have 2 nickels

And you have 7 dimes

the transitive property of equality.

step-by-step explanation:

the correct answer is:

the transitive property of equality.

explanation:

we know that  ∠bcd is congruent to  ∠pbc. we also know that  ∠pbc is congruent to  ∠bad.

we can substitute  ∠bad for  ∠pbc in the first angle congruence statement to give us:

∠bcd is congruent to  ∠bad.

algebraically, the transitive property states if a=b and b=c, then a=c. it basically allows us to substitute equal values. since that is what we did, this is the transitive property.
