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

Ymorist [56]

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

F(x) = 5x2 − 70x + 258. Complete the square.

astraxan [27]

5(x^2 - 14x + 258/5)
= 5((x-7)^2 -49+258/5)
= 5((x-7)^2 + 13/5)
= 5(x-7)^2 + 13
I belive this is how it should be done
