3x - 4 = 5x - 38
34 = 2x
x = 17
3(17) - 4 = 51 - 4
angle 3 = 47
180 - 47 = 133
Just plug in each of the (x) values into each of the expressions. For example:
2/3(7) + 5 = (14/3) + 5 = 29/3
Please only post one of you questions.
Slightly confused on this, but basically find the GCF of 28 and 20. This should be the amount of students in each group. Then you should be able to finish your problem.
Point slope form:
y - y1 = m(x - x1)
I can't help you on all of your questions, only the ones you actually need help on.
You just need answers for your homework now. Please think about the question before asking for help.
Draw a graph to see why, but the answer is x = 9
1 5/8 - 8/9 =
13/8 - 8/9 =
117/72 - 64/72 =
(117 - 64)/72 =
53/72
