Kevin has 23 dimes and quarters in his piggy bank. if the value of these coins is $4.55, how many dimes and quarters does he have? set up and solve a system of equations to solve the problem

We know that the value of 1 dime is $0.1. We also know that $ 1 =100 cents

Now, we know that Kevin has 23 dimes in his piggy bank. We also, know that the total amount in Kevin's piggy bank is $4.55. Thus, we need to find the amount of cents in Kevin's piggy bank. To do that we will have to set up the following equation.

(Value of one dime)x(number of dimes)+(value of one cent)x(number of cents)=$4.55

Let the number of cents be. Then our equation will become:

$0.1 x 23 + ($ 0.01) x =$4.55

Thus, there are 225 cents in Kevin's piggy bank

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
