Answer:
A and c
Step-by-step explanation:
multiply the 3 to both parts of equation
Let’s make x = # of nickels. Then 3x = # of dimes and 3x+6 = # of pennies. A nickel is 5 cents, a dime is 10 cents and a penny is 1 cent.
The money she has should be .05(x) + .10(3x) + .01(3x+6) = 4.62 or to make it simpler: 5(x) + 10(3x) + 1(3x+6) = 462.
5x + 30x + 3x + 6 = 462
38x + 6 = 462
38x = 456
x = 12.
So she has 12 nickels (12 * $0.05 = $0.60), 36 dimes (36 * $0.10 = $3.60) and 42 pennies (42 * $0.01 = $0.42). $3.60 + $0.60 + $0.42 = $4.62.
Answer:
An equation that indicates you can spend exactly $45 per day for rental fees is, 
Step-by-step explanation:
Let x represents the days and y represents total the rental fees.
As per the statement:
you can spend exactly $45 per day for rental fees.
In 1 day you spend = $45 rental fees.
then
in x days = 45 x
we have to find an equation that indicates you can spend exactly $45 per day for rental fees
since, y represents the total rental fees,.
⇒ y= 45x
Therefore, an equation that indicates you can spend exactly $45 per day for rental fees is, 
Jessie = Todd + 6
Todd = Ryan -2
if Ryan = r
so Todd = r-2
then Jessie = (r-2) + 6 = r-4 years old
