Answer:

c. y = -35*x + 105

Step-by-step explanation:

Lo que demos hacer es calcular los puntos cuando x = 0 y cuando x = 3, es decir el inicio y el fin del recorrido.

Cuando x es igual 0, y = 105, por lo tanto, la función sería:

y = A*x + 105

Cuando x = 3, y = 0, por lo tanto:

0 = 3*A + 105

resolvemos para A:

3*A = -105

A = -105/3

A = -35

Por lo tanto la función es:

y = -35*x + 105

es decir, la opción c.

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

joja [24]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
