Distributive simplifiy 8(y+3)

Answers

Answer 1
Answer: well, you distribute the 8 to both terms since it is being multiplied.
8 * y = 8y
8 * 3 = 24
so the ending equation should be 8y + 24
Answer 2
Answer: 8y+24 is the correct answer unless you are trying to get y alone

Answer:

a.) 3.236 or -1.236

Step-by-step explanation:

Used an online calculator for this answer...

Using the Quadratic Formula where

x = ( -b \pm √(b^2 - 4ac))/( 2a )\nx = ( -(-6) \pm √((-6)^2 - 4(3)(-12)))/( 2(3) )\nx = ( 6 \pm √(36 - -144))/( 6 )\nx = ( 6 \pm √(180))/( 6 )

The discriminant b^2−4ac > 0

so, there are two real roots.

Simplify the radical...

x = ( 6 \pm 6√(5)\, )/( 6 )\nx = ( 6 )/( 6 ) \pm (6√(5)\, )/( 6 )\nx = 1 \pm √(5)\,

This simplifies to...

x = 3.23607\nx = -1.23607

2x - 3y = 1x = y + 2

Answer:

we have x = y +2

now we put that value in other eq.

2(y+2)-3y = 1

2y+4-3y = 1

2y-3y = 1-4

-y= -3 (cut the signs on both side)

y= 3

now we put y value in the other given equation

x = 3+2

x = 5

we have y as 3 and x as 5.

which is a better buy? A 24-ounce bottle of shampoo for $9.00 or a 16- ounce bottle of shampoo for $7

Answers

The answer is the 16 - ounce bottle of shampoo for $7. This is how I did it:
I divided the price and the ounce of shampoo in the bottle.
24/9 = $2.67 per ounce and 16/7 = $2.29 per ounce
Now you can see which one is a cheaper price. Hope this helped you =)

The better buy would be the 16- ounce bottle of shampoo for $7
