Answer:

x = 9

Step-by-step explanation:

Opposite sides of a parallelogram are equal.

16x - 15 = 11x + 30 Subtract 11x from both sides

16x - 11x - 15 = 30 Combine the left

5x - 15 = 30 Add 15 to both sides

5x = 30 + 15 Combine the right

5x = 45 Divide by 5

5x/5 = 45/5

x = 9

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
