Write a division problem that has a 3-digit dividend and a divisor between 10 and 20. Show how to solve it by drawing a quick pi
stich3 [128]

Answer:

In the division problem,

The number which is divided is called dividend,

While, the number which divides, is called divisor,

Let dividend = 150 ( a three digit number ),

Divisor = 15 ( a number between 10 and 12 ),

So, the problem would be,

150\div 15

In the below figure,

Take a grid that shows 150,

Divide this grid such that each box represents 15,

Thus, there are such 10 boxes,

That is,

150\div 15 = 10

10) Choose the solution for each linear system.
hodyreva [135]

Answer:

<h2>10.  C. (2, -1)</h2><h2>11.  B. (-2, -4)</h2>

Step-by-step explanation:

10.

\left \{ {{x-2y=4} \atop {4x+2y+6}} \right.

The y values cancel out if you add the equations

5x = 10

x = 2

plug in x

2 - 2y = 4

-2y = 2

y=-1

Answer: C. (2, -1)

11.

\left \{ {{6x-2y=-4} \atop {-4x+3y=-4}} \right.

In order to get terms to cancel out, multiply the top by 3 and bottom by 2

\left \{ {{18x-6y=-12} \atop {-8x+6y=-8}} \right.

The y values cancel out if you add the equations

10x = -20

x = -2

plug in x

6(-2) - 2y = -4

-12 - 2y = -4

-2y = 8

y = -4

Answer: B. (-2, -4)
