m is equal to the slope,
and b is the y intercept.

Y= (1/2)x+ (-1)

or
Y = (1/2)x-1

Sarah made a necklace using 5 times as many blue beads as white beads. She used a total of 30 beads. How many blue beads did Sar

iogann1982 [59]

Let

x-------> the numbers of blue beads

y-------> the numbers of white beads

we know that

$x+y=30$ --------> equation $1$

$x=5y$ --------> equation $2$

Substitute equation $2$ in equation $1$

$(5y)+y=30\\ 6y=30\\ y=30/6\\ y=5$

Find the value of x

$x+y=30\\ x+5=30\\ x=30-5\\ x=25$

therefore

the answer is

the numbers of blue beads is $25$
