Answer:
B
Step-by-step explanation:
<STR = <SRT Given the markings of the triangle
<STR + <STU = 180 Supplementary angles
(2x - 9) + 7x = 180 Remove the brackets
2x - 9 + 7x = 180 Combine
9x - 9 = 180 Add 9 to both sides
9x = 180 + 9 Combine
9x = 189 Divide by 9
9x/9 = 189/9
x = 21

To find the answer, you need to determine what the difference is. In this case, the difference is 6.
134 - 128 = 6
140 - 134 = 6
146 - 140 = 6
152 - 146 = 6
So, to find the answer you would add 6 to the next set of numbers to continue the pattern. For example -
152 + 6 = 158
158 + 6 = 164
Answer:
1/3 is your answer.
Step-by-step explanation:
What you do is you have to make the denominator the same.
-27/45(-25/45)
1/3 is your answer.
1. 504=3x
x=168
2. 64=20m
m=3.2
