Answer:

-80/81

Step-by-step explanation:

(9^11)/(9^(10))=9^(11-10)=9

(9^10)/(9^(11))=9^(10-11)=9^(-1)=1/9

Difference is 1/9 - 9=-80/81

The angles of a triangle add up to 180 degrees

65 + 3x - 10 + 2x = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 125/5
x = 25 <====

m < B = 3x - 10 = 3(25) - 10 = 75 - 10 = 65 <== B is 65 degrees
m < C = 2x......= 2(25) = 50 <== C is 50

Use the distributive property to simplify the expression.
zepelin [54]

Option D

Using the distributive property, -7(8x – 3) + x = -55x + 21

<em><u>Solution:</u></em>

Given that we have to use distributive property to simplify the given expression

Given expression is:

-7(8x – 3) + x

Let us first understand about distributive property

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

<em><u>The distributive property is represented as:</u></em>

a(b + c) = ab + ac

Apply this property in given expression for -7(8x - 3)

-7(8x - 3) = (- 7 \times 8x) + (-7 \times -3)\\\\-7(8x - 3) = -56x +21

Apply the above result in given expression

-7(8x - 3) + x = -56x + 21 + x

Combine the like terms. Add -56x and x

-7(8x - 3) + x = -56x + 21 + x = -55x + 21\\\\-7(8x - 3) + x = -55x + 21

Thus the given expression is simplified. Option D is correct
