Answer:

3

Step by Step:

Subtract the tip ($6) from the total ($39)

11x=33

Then divide 33 by 11, leaving you with the value of x.

x=3

The lesson was 3 hours long.

How do you divide integers
Tom [10]

You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.

<span>
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.</span>

<span>Positive x positive = positive 
Negative x negative = positive</span>

<span>When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.</span>

<span>Positive x negative = negative
Negative x positive = negative</span>

<span>When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.</span>

<span>Positive ÷ positive = positive
Negative ÷ negative = positive</span>

<span>When you divide two integers with different signs, the result is always negative. Just divide the absolute values and make the answer negative.</span>

Maurinko [17]

Answer:

X = 33,669.78 ft

Y = 15285.76 ft

Step-by-step explanation:

Given data:

let x be the distance btwn arch and plane

and y be the distance btwn  ground point  and arch y

we know that

cos\theta =  \frac{adjacent}{hypotaneous}

cos(27) = \frac{30,000}{x}

xcos27 = 30000

x = \frac{30000}{cos 27}

x = 33,669.78 ft

b) we knwo that

tan \theta  = \frac{opposite}{adjacent}

tan 27 = \frac{y}{30000}

y = tan(27) (30000)

y = 15285.76 ft

Ksenya-84 [330]
20+4x=76  subtract 20 from both sides

4x=56  divide both sides by 4

x=14

So he was driving at 55+14=69 mph
