Answer:

-1 is the answer

Step-by-step explanation:

the question is 3(y-1)=y-5

so, we open the bracets and multiply

so it becomes 3y-3 = y-5

now, we transpose

3y-y =-5+3

2y = -2

y= -2/2 = -1

Answer:

y = -1

Step-by-step explanation:

3(y-1)=y-5\\\\3y-3=y-5\\\\3y-3+3=y-5+3\\\\3y=y-2\\\\3y-y=y-y-2\\\\2y=-2\\\\\frac{2y=-2}{2}\\\\\boxed{y=-1}

Hope this helps.

if a = first term

and constant number = d

then

GP is given by

a,a r , a r^2 ,a r^3 .............and so on

in first

a = 1/2

Ryan has $0.75 worth of pennies and nickels. He has 3 more nickels than pennies. Determine the number of pennies and the number
ziro4ka [17]

Answer:

He has 10 pennies and 13 nickels.

Step-by-step explanation:

A nickel is worth 0.05 while a pennie is worth 0.01. Since Ryah has 0.75 in nickels and pennies, then the amount he has can be described by the following equation:

0.05*nickel + 0.01*pennie = 0.75

We know that he has 3 times more nickels than pennies, therefore:

nickel = pennie + 3

Using that information on the first equation we have:

0.05*(pennie+3) + 0.01*pennie = 0.75

0.05*pennie + 0.15 + 0.01*pennie = 0.75

0.06*pennie = 0.75 - 0.15

0.06*pennie = 0.6

pennie = 10

nickel = 10 + 3 = 13

He has 10 pennies and 13 nickels.
