If you want it to be easier to add, just do it like this: 200,000+ 30,000= 230,000
If you want me to be more specific, put this: 201,000+ 29,000= 230,000
It really doesn't matter because both estimates are the same answer, so you can put whichever one. Hope this helps!!!! :)

Answer:

The estimate of  200,629+28,542 is 230000.

Step-by-step explanation:

Given : Expression 200,629+28,542

To find : What is the estimate for expression ?

Solution :

Estimate the number 200,629 by rounding we get approximately

200629\approx 200000

Estimate the number 28,542 by rounding we get approximately

28542\approx 30000

So, If we add these number we get

200000+30000=230000

Please please please help if you can!<br> Thank you!!

Answer:

There are 16 rows of seats in the auditorium.

Step-by-step explanation:

Jose is correct in writing out 416 = 2x² - 6x.

Rewriting this in descending order by powers of x, we get:

2x² - 6x - 416 = 0  

Dividing all four terms by 2 simplifies this equation to x² - 3x - 208 = 0.  This equation, in turn, factors to (x + 13)(x - 16) = 0.  The only reasonable answer is x = 16.  Jose's solutions are incorrect.

There are 16 rows of seats in the auditorium.

The number of seats per row is 416/16, or 26.

irina [24]

Answer:

Step-by-step explanation:

Area of a parallelogram is given as the multiplication of its length by that of its height or breadth, however you call it.

In this question, you didn't state the length nor the breadth or height. You just listed the answers. It's very hard knowing the answer without having its dimensions. However, I can tell you that on the diagram or drawing you have there with you, multiply the two distance given to you together, it ought to give you one of the four options you listed above. Be it 168, 140, 130 or even 120 square inches.

The length of a rectangle is 1 more than 3 times the width . If the perimeter of the rectangle is 18 units , what’s it’s area?
nika2105 [10]

Answer:

14 square units

Step-by-step explanation:

You need to know the formulas for the perimeter of a rectangle and the area of a rectangle, which are

2L + 2W - P     where L is the length, W is the width, and P is the perimeter

and

A = LW      

So we need to find the length and width to find the area


Step 1:  Write equations out of the given information

"The length of a rectangle is 1 more than 3 times the width" can be rewritten as

L = 3W + 1


"the perimeter of the rectangle is 18 units" can be rewritten as

2L + 2W = 18


Step 2:  Plug the first formula into the second one and solve

      2(3W + 1) + 2W = 18

Simplify...

      6W + 2 + 2W = 18

Combine like terms and subtract 2 from both sides

     8W = 16

Divide both sides by 8 to isolate the W

   W = 2


Step 3:  

Plug W = 2 into the formula for L and solve for L

  L = 3(2) + 1

      L = 6 + 1

        L = 7


Step 4:  Use the length and width to calculate the area

A = LW

  A = (7)(2)

     A = 14 units squared
