Answer:
n = nickels, q = quarters
Equation 1: n+q=30
Equation 2: 0.05n+0.25q = 3.30
Step-by-step explanation:
From equation 1, n = 30-q
Substitute in Equation 2:
0.05(30-q) + 0.25q = 3.30
1.5 - 0.05q + 0.25q = 3.30
0.2q = 1.8
q = 9
Substitute in new equation:
n = 30-9
n = 21
It is important to note a nickel is worth 5 cents and a quarter is 25 cents. This helps us build the equations.
This is easy all you do to find the surface area is to multiply base the number that is across by the height the number that shows the height.The you just multiply those 2 and you got the surface area.For number one the answer is,20.For two the answer is, 6.Need more help ask me under in the comments. If this was helpful please give me brainiest answer. Hope this Helps :D
