Lisa had 3 dollars. she went to the bank and exchanged the 3 dollars for 30 dimes. describe the relationship between the value of a dollar and the value of a dime

Relationship between the value of a dollar and the value of a dime is:

1 dollar= 10 dimes

or 1 dime= 0.1 dollars

Step-by-step explanation:

We are given that:

Lisa exchanged  3 dollars for 30 dimes

3 dollars= 30 dimes

Dividing both sides by 3, we get

i.e. 1 dollar= 10 dimes

or 1 dime= 0.1 dollars

Hence, relationship between the value of a dollar and the value of a dime is:

1 dollar= 10 dimes

or 1 dime= 0.1 dollars

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
