So the trapezoid has 2 parallel sides making segments AD and BC  transversals

Therefore making angle c and angle b add up to 180

(180-3x) + 3x + 180-9x +9x

180 +12x = 360

180= 12x
x= 15

NEED HELP ASAP. I don not understand why I'm wrong. What is the right answer???
hammer [34]

Answer:

<u>Answer</u><u>:</u><u> </u><u>3</u><u>5</u><u>/</u><u>1</u><u>8</u>

Step-by-step explanation:

\frac{ \{ \frac{3}{4} -  \frac{5}{2}  \} }{ \{ \frac{3}{5}  -  \frac{3}{2}  \}}   =  \frac{( -  \frac{7}{4} )}{ (-  \frac{9}{10} )}  \\  \\   =  \frac{7}{4}  \div  \frac{9}{10}

use the reciprocal of 9/10 :

=  \frac{7}{4}  \times  \frac{10}{9}  \\  \\  =  \frac{35}{18}

Max can type 160 words in 5 minutes. How long would it take him to type 400 words? * A. 12.50 minB. 13 minC. 10.50 minD. 12 min
blagie [28]
To find how long it would take him, one has to divide 400 by 160 and then multiply 5 by what that number is. You multiply 5 by the quotient because that is the number that would make it proportional. 400/160 x 5 is 12.5, meaning that the answer is 12.5 minutes, or A.
