Answer:
Number of nickels is 10
Number of dimes is 10
Step-by-step explanation:
Let's assume
number of nickels =n
number of dimes =d
Nicole has 20 coins in her purse
so,
we know that
1 nickel =0.20 dollar
1 dimes =0.10 dollar
total she has $3 in her purse
so, we can get another equation
we get system of equations as
We can isolate n from first and plug into second
now, we can solve for d
now, we can find n
So,
Number of nickels is 10
Number of dimes is 10

Is a y = Mx + b equations it’s B because c is our y and it look like it going up by 12 so every 1 Cube is 12 towers
2x²+12x, distribute the -4x to the parenthesis then simplify like terms.
Y=mx+b
Y= -14(x-5)+4
Y= -14x+70+4
Y= -14x+74
