Answer:

Number 3 has no solution

Step-by-step explanation:

First you need to divide both sides of the equation 12x - 12y = -12 by 4

-3x + 3y = -3

12x - 12y = -12

-3x + 3y = -3

3x - 3y = -3

Then you need to eliminate one variable by adding the equations.

0 = -6

this statement is false, and therefore has no solution.

Doors for the small cabinets are 17.5 inches long. Doors for the large cabinets are 2.7 times as long as the doors for the small
AleksAgata [21]

Answer:

3 large doors

Step-by-step explanation:

Given

Board = 12ft

Represent small door with S and large with L

S = 17.5\ in

From the question, we understand that;

L = 2.7 * S

So, we have that

L = 2.7 * 17.5\ in

L = 47.25\ in

Required

Determine the number of Large doors that can be cut from the board

To do this, we simply divide the size of the board by the size of the large cabinet

i.e.

Number = \frac{Board}{L}

Number = \frac{12\ ft}{47.25\ in}

Convert feet to inches

Number = \frac{12 * 12\ in}{47.25\ in}

Number = \frac{144\ in}{47.25\ in}

Number = 3.04761904762

Get the integer part of the decimal

Number = 3

Hence:

3 large doors can be gotten from the board

samantha has 20 marbles paul has m marbles. Of samantha has 6 times as many marbles as paul, write an equation to show how many
Morgarella [4.7K]

Answer:

20 = 6m  or  m = 20/6 = 10/3

Step-by-step explanation:

Let's say Samantha has s marbles and Paul has m marbles.

We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.

Substitute 20 in for s:

20 = 6m

m = 20/6

Thus, the equation is m = 20/6.
