what number is 11 less than the other number if there's some is increased by 8 the result is 71 find the numbers ​
Keith_Richards [23]

Answer:

26,37

Step-by-step explanation:

m=n-11

     m-n=-11-------(1)

m+n+8=71--------(2)

(1)+(2)

(m-n)+(m+n+8)=-11+71

m-n+m+n+8=-11+71

2m+8=60

2m=52

m=26

by substitute in (1)

          26-n=-11

         -n=-11-26

         n=37

Round the numbers to the highest place value.
Kaylis [27]

Answer:

2398 = 2000

56254 = 60000

71563 = 70000

33021 = 30000

9645 = 10000

Step-by-step explanation:

Given

2398

56254

71563

33021

9645

Required

Round up to highest place value​

2398

Highest place value here is thousand.

So:

2398 = 2000, when approximated

56254

Highest place value here is ten thousand.

So:

56254 = 60000, when approximated

71563

Highest place value here is ten thousand.

So:

71563 = 70000 when approximated

33021

Highest place value here is ten thousand.

So:

33021 = 30000 when approximated

9645

Highest place value here is ten thousand.

So:

9645 = 10000 when approximated

How do you solve problems with proportions
Anuta_ua [19.1K]

Answer:

Step-by-step explanation:

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Forty-five roses, plus some number of daffodils and tulips, are blooming in a garden.
stellarik [79]

The maximum number of of bouquets the gardener could have made is 3

<h3>How to find unknown parameter</h3>

Total = 45

let

  • number of daffodils = x
  • number of tulips = y

Roses = 4x

Tulips = 4x + 15

Total = roses + daffodils + tulips

45 = 4x + x + (4x + 15)

45 = 5x + 4x + 15

45 = 9x + 15

45 - 15 = 9x

30 = 9x

x = 30/9

x = 3.33333333333333

Approximately,

x = 3

Let more about equation:

Suppose you have 40 meters of fencing what is the greatest rectangular area that you can enclose
Gelneren [198K]
It'd help if you could sketch this situation.  Note that the area of a rectangle is equal to the product of its width and length:  A = L W.

Consider the perimeter of this rectangular area.  It's P = 2 L + 2 W.  Note that P = 40 meters in this problem.

Thus, if we choose to use W as our independent variable, then P = 40 meters = 2 L + 2 W.  Let's express L in terms of W.  Divide both sides of the following equation by 2:  40 = 2 L + 2 W.  We get 20 = L + W.  Thus, L = 20 - w.

Then the area of the rectangle is  A = ( 20 - W)*W.

Multiply this out.  Your result will be a quadratic equation.  Graph this quadratic equation (in other words, graph the function that represents the area of the rectangle).  For which W value is the area at its maximum?  

Alternatively, find the vertex of this graph:  remember that the x- (or W-) coordinate  of the vertex is given by

W = -b/(2a), where a is the coefficient of W^2 an b is the coefficient of W in your quadratic equation.

Finally, substitute this value of W into your quadratic equation, to calculate the maximum area.
