Answer:
Step-by-step explanation:
Vertically Opposite Angles are equal..
so,
8.1 + 6.0 + 4.7 + 6.9 + 5.6 + 7.7 + 6.3 + 7.8 + 6.1 + 9.2 = 68.4/9 = 7.6
The first one = 60.3 so it can’t be that one.
the second one = 34.5 so not that one either
the third one = 60.3
and the last one = 28.3
-3x + 7 = -1
-3x = -8
x = 8/3
In order to solve for x, you must isolate the variable. Because -1 and 7 are like terms, use inverse operations to subtract 7 from both sides. Then, divide both sides by -3. This should get you x = 8/3, which can’t be reduced any more (unless you convert to decimal, which is about 2.666666…) Feel free to comment any questions you have! Always happy to help :)
