Answer:
Property of Addition
Step-by-step explanation:
For all real numbers x, y, and z ,
if x = y, then x + z = y + z .
if a = 5, and 5 + z = 14, so a + z = 14
Answer:
your work is hard
Step-by-step explanation:
<span> the 1st letter can be put into any of the 5 envelopes,
the 2nd letter in any of the 4 r3maing envelopes, & so on,
giving a total of 5*4*3*2*1 = 120 ways,
while there is just 1 way to insert all letters into correct envelopes
Pr = 1/120</span>
Answer:
125
Step-by-step explanation:
You can find the interior angle next to the angle with the value of 100, because a straight line has an angle of 180, so that angle would be 80. You can do the same with the interior angle next to 135, with that angle having a value of 45.
The interior angles of a triangle always have the sum of 180, so to get the last interior angle add 80+45 and then subtract that from 180. That angle would be 55.
To get Y take the value of the interior angle subtract 55 from 180, which would be 125.
To answer this question, make a setup like this;
1 5
-- ÷ --
3 1
now change it to multiplication.
1 1 1
-- * -- = -----
<span>3 5 15
</span>
multiply across, and your answer is 1/15.
