Answer 2

Answer:

10x + 18

You cancel out the lowest variable term to only have one variable term.

Step-by-step explanation:

-3x+3 then do 7x+3

10x + 18

You cancel out the lowest variable term to only have one variable term.

Each nested cart adds 1.5 feet to the length of the row.



If the store design allows for 43 feet for each row, how many total carts fit in a row?

_____ total carts fit in a row.

Explain your reasoning for the number of total carts that can fit in a row.

Answers

I believe your answer might be 28.6 carts, but I’m not fully sure. Each cart adds 1.5 feet of length, and each row can only have 43 feet, so I believe you divide 23 by 1.5 to find out how many carts can fit. Sorry if I’m wrong!

-2(z+3)-z=-z-4(z+2)
solve for z quickly please! will give brainliest

Answers

Answer:

[tex] \sf z = - \dfrac{2}{3} [/tex]

Step-by-step explanation:

Solve for z:

[tex] \longrightarrow [/tex] -2(z + 3) = -z - 4(z + 2)

-4(z + 2) = -4z - 8:

[tex] \longrightarrow [/tex] -2(z + 3) = -z -4z - 8

Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:

[tex] \longrightarrow [/tex] -2(z + 3) = (-z - 4z) - 8

-z - 4z = -5z:

[tex] \longrightarrow [/tex] -2 (z + 3) = -5z - 8

Expand out terms of the left hand side:

[tex] \longrightarrow [/tex] -2z - 6 = -5 z - 8

Add 5z to both sides:

[tex] \longrightarrow [/tex] (5z - 2z) - 6 = (5z - 5z) - 8

5z - 5z = 0:

[tex] \longrightarrow [/tex] (5z - 2z) - 6 = -8

5z - 2z = 3z:

[tex] \longrightarrow [/tex] 3z - 6 = -8

Add 6 to both sides:

[tex] \longrightarrow [/tex] 3z + (6 - 6) = 6 - 8

6 - 6 = 0:

[tex] \longrightarrow [/tex] 3z = 6 - 8

6 - 8 = -2:

[tex] \longrightarrow [/tex] 3z = -2

Divide both sides of 3z = -2 by 3:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}z = - \dfrac{2}{3} [/tex]

[tex] \sf \dfrac{3}{3} = 1 :[/tex]

[tex] \longrightarrow [/tex] [tex] \sf z = - \dfrac{2}{3} [/tex]
