Answer:

28$

Step-by-step explanation:

4$ per pack 4×3 =12 so 28$

Answer:

$12 more dollars for three packs. Sorry for the slow answer, my mouse keeps disconnecting.

Step-by-step explanation:

First, you need to divide 16 by 4 to get the unit price.

16 ÷ 4 = 4

This means that one pack is $4.

Fill the first column with the number of packs(1), and then the price of it($4).

For the second column, multiply $4 by 2 or just add $4.

4 x 2 = 8

Fill the second column with the number of packs(2), and then the price of them($8).

Finally, multiply $4 by 3, or add $4 to $8.

4 x 3 = 12

Fill the third column with the number of packs(3), and then the price of them($12).

The answer is D according to kinetic molecular theory. Hope this helps!

Answer: In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.

Answer: 34

Step-by-step explanation:

8*6= 48 8*5=40 2 squared=4 40+48= 88 88/4=22

22+12= 34

It would be 34

Because 8(6+5) = 48+40= 88 over 4 which is 22 then you would do 6(2) which is 12 so 22+12 is 34

Answers

To find x-intercept substitute 0 for y and solve for x
-6x + 3(0) = -7
Simplify
-6x=-7
Divide each side by -6
-6x ÷ -6 = -7 ÷ -6
x = 7/6
X = 7/6 is your x intercept
-------------------------------------
To find y-intercept substitute 0 for x and solve for y
-6(0)+3y=-7
Simplify
3y=-7
Divide each side by 3
3y ÷ 3 = -7 ÷ 3
y = -7/3
Y = -7/3 is your y-intercept
