Unit rate is total price divided by quantity. This gives you the cost for 1 item.

Unit costs:

2.99 / 6 = 0.4983 each

4.49 / 9 = 0.4988 each

5.99 / 12 = 0.4991 each

3.49 / 8 = 0.4362 each

The Best Buy would be the one with the lowest unit price.

The Best Buy would be 3.49 for 8 candles.

Y=6x+20 substitution​
Oksana_A [137]

Answer:

-10/3 or -3.33

Step-by-step explanation:

substitute 0 for y

0 = 6x + 20  

-20 = 6x + 20 - 20               subtract 20 on both sides  

-20 = 6x                               divide by 6 on each side

-20/6 = 6x/6

x = -20/6                             simplify

x =   -10/3

Solve the system of equations using elimination.<br><br> 4x - 7y = 5<br> 9x – 7y = –15
Anni [7]

Step-by-step explanation:

We have to get one positive 7y so,

4x-7y=5

9x-7y=-15

multiply anyone of the equation by -1. I choose the first one so,

4x+7y=-5

9x-7y=-15

we can now cancel the y's so the equation will be left with

-4x=-5

9x=-15

add the equations

5x=-20

divide by 5 n u get

x=-4

now plug in the x value in any one of the

equations

I choose the first one so,

4(-4)-7y=5

-16-7y=5

add 16 to both sides

-7y=21

divide by -7

y=-3.

finally check.
