kkurt [141]

Answer:

Correct answer: Nickels x = 11 and pennies y = 9

Step-by-step explanation:

We will first define the variables in the system:

Let be nickels x and pennies y

We will form a system to solve this problem:

5 x + 1 y = 64

x + y = 20/ · (-1)

we will first multiply the second equation by -1 and add it by the first and get:

4 x = 44 ⇒ x = 44 / 4 = 11 nickels

x = 11 nickels

from the other we get y

y = 20 - x = 20 - 11 = 9 pennies

y = 9 pennies

God is with you!!!

Aumentar / tamanho inicial × 100

Aumento = 14489 focos de incêndio - 4660 focos de incêndio

= 9829 focos de incêndio

Aumento percentual = 9829/4660 × 100

= 210.92274678 %
