<u><em>Answer:</em></u>
-9
<u><em>Explanation:</em></u>
<u>From the first three </u><span><u>triominoes, we can note that:</u>
number on center = -first base - second base + vertex
<u>This is verified as follows:</u>
<u>For the first one:</u>
The two bases are 7 and 9 and the vertex is 1
- first base - second base + vertex = -7 -9 + 1 = -16 + 1 = -15
<u>For the second one:</u>
The two bases are 0 and 9 and the vertex is 8
- first base - second base + vertex = -0 -9 + 8 = -9 + 8 = -1
<u>For the third one:</u>
The two bases are 6 and 4 and the vertex is 2
- first base - second base + vertex = -6 - 4 + 2 = -10 + 2 = -8
<u>Applying the same procedure on the last one:</u>
The two bases are 7 and 2 and the vertex is 0
-first base - second base + vertex = -7 - 2 + 0 = -9 + 0 = -9
Hope this helps :)</span>
Answer:
k = 6
Step-by-step explanation:
X=162, if you multiply 18*9 which is the way to get the answer you get 162
Answer:
60 is 5$ of 1200
Step-by-step explanation:
Find the value of the ratio 60/1200 and then multiply the result by 100%:
(1/20)(100%) = 5%
5(x + 27) >= 6(x + 26)
5x + 135 >= 6x + 156
-x >= 21
x <= -21
Answer: Choice B.
