The sum of two numbers is 65. The larger number is 23 more than the smaller number . What are the numbers ?

KiRa [710]

Let's represent the smaller number by x and the larger number x+23
x+x+23=65 x+23=21+23=44 So the two numbers are 21 and 44
2x+23=65
2x+23-23=65-23
2x=42
2x/2=42/2
x=21

Answer:

$\left[\begin{array}{cc}12&1\\-4&1\\-11&28\end{array}\right]$

Step-by-step explanation:

The element at row i column j in the product is the dot-product of row i of the first matrix and column j of the second matrix. For example, row 2 column 1 of the product is ...

(row 2) · (column 1)

[3, -2, 4] · [2, 7, 1] = (3)(2) +(-2)(7) +(4)(1) = 6 -14 +4 = -4

The attachment shows the complete product matrix. It is convenient to let a spreadsheet or graphing calculator do the tedious repetitive arithmetic.

Rina8888 [55]

To solve this problem, we can use cross multiplication:

First, we can to convert inches into feet so...

5 inches = 0.416667 ft

7 inches = 0.583333 ft

(0.416667 ft/ 0.583333 ft) = (12 ft/ x ft)

x = 16.8 ft

So the actual width is 16.8 ft.

Hope this helps!
