Answer:

x = 105

Step-by-step explanation:

Sum of n-sided polygon = (n - 2)*180

The polygon given is a 7-sided polygon, therefore substitute n = 7 into (n - 2)*180

Sum of the polygon = (7 - 2)*180 = 900°

Thus:

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900

Add like terms

2x + 690 = 900

2x = 900 - 690

2x = 210

x = 210/2

x = 105

Answer:

6

Step-by-step explanation:

Let the two integers be a and b.

The difference of them is 26. Thus:

a-b=26

One of them (let's use a) is 2 more than 5 times the other. Thus:

a=2+5b

Substitute:

a-b=26\\(2+5b)-b=26

Combine like terms:

4b+2=26

Subtract 2 from both sides:

4b=24

Divide by 4:

b=6

And the second number is:

a-b=26\\a-6=26

Add 6 to both sides:

a=32

So, our two numbers are 32 and 6

And the smaller integer is 6.

And we're done :)

1.Write an example of how the product of two different irrational numbers can be a rational number.
Digiron [165]

Answer:

1 "The product of two irrational numbers is SOMETIMES irrational." The product of two irrational numbers, in some cases, will be irrational. However, it is possible that some irrational numbers may multiply to form a rational product.

2 The quotient has widespread use throughout mathematics, and is commonly referred to as a fraction or a ratio. For example, when dividing twenty (the dividend) by three (the divisor), the quotient is six and two thirds. In this sense, a quotient is the ratio of a dividend to its divisor.

3 The sum of two irrational numbers, in some cases, will be irrational. However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational. "The product of two irrational numbers is SOMETIMES irrational."
