Answer:

1/15

Step-by-step explanation:

(5/7 - 1). [2/3 + (1/6 - 1/9), 18/5 + 1/15] - (2/7 + 1/3). (-7/13)

Use order of operations; PEMDAS.

Start with the inner parentheses:-

= (5/7 - 1). [2/3 + 1/18. 18/5+ 1/15] - (2/7 + 1/3). (-7/13).  Now the other parentheses:-

= (-2/7). ( 2/3 + 1/5  + 1/15) - (13/21).(-7/13)

= -2/7 . 14/15 + 7/21

= -2/7 . 14/15 + 1/3

= -4/15 + 1/3

= 1/15 (answer)

Answer:

(5/7 - 1) * (2/3 + (1/6 - 1/9) * 18/5 + 1/15) - (2/7 + 1/3) * (-7/13)

= (5/7 - 7/7) * (2/3 + (3/18 - 2/18) * 18/5 + 1/15) - (6/21 + 7/21) * (-7/13)

= (-2/7) * (2/3 + 1/18 * 18/5 + 1/15) - 13/21 * (-7/13)

= (-2/7) * (2/3 + 1/5 + 1/15) + 7/21

= (-2/7) * (10/15 + 3/15 + 1/15) + 1/3

= (-2/7) * 14/15 + 1/3

= -4/15 + 1/3

= -4/15 + 5/15

= 1/15

Find the values of x and y
const2013 [10]

Answer:

x = 79 y = 22

Step-by-step explanation:

x would be the same as the other side so 79 * 2 would be 158. A whole triangle is 180. 180 - 158 = 22

Match the fraction with its equivalent decimal form of the number.
bagirrra123 [75]

Answer:

  see below

Step-by-step explanation:

The overbar on decimal digits means they repeat forever.

Any fraction with a denominator consisting of powers of 2 and/or 5 will terminate. These can be converted to decimal by multiplying the fraction by a number to make the denominator an appropriate power of ten.

  1 2/3 = 1.66666666666... repeating

  1 3/5 = 1 (3·2)/(5·2) = 1 6/10 = 1.6

  1 1/4 = 1 (1·25)/(4·25) = 1 25/100 = 1.25

  1 33/50 = 1 (33·2)/(50·2) = 1 66/100 = 1.66

Of course, your calculator can tell you the decimal equivalents, too.
