A pile of 42 coins worth $4.90, consisting of nickels and quarters. How many nickels are there?

Mathematics
1 answer:
Ymorist [56]2 years ago
6 0

Answer:14

Step-by-step explanation:

A nickel is 5 cents (20% of dollar)

and a quarter is 25 cents (25% of dollar)

We have given a pile of 42 coins worth of $4.90

Let x be the no nickels and

y be the no of quarter

therefore

x+y=42    -----1

\frac{x}{4}+\frac{y}{20}=4.90 ---2

Solving \left ( 1\right )&\left ( 2\right ) we get

x=14 & y=28

Therefore no of nickels is 14 & no of quarters is 28

What is the graph of the function? <br><br> f(x) = 2x2
spayn [35]
Let's plug in a few points to see which graph belongs to the function f(x) = 2x^2

Let's say x =0, let's find y!
2(0)^2 = 2(0) = 0

So one point on our line is (0.0)

Just finding this point right here eliminates 3 of the answer choices. Your answer is the graph that goes through the point (0,0)

For your added convenience, I have attached the graph. :)
