Answer:
-2 21/50
Step-by-step explanation:
-2.42
-2 42/100 = -2 21/50
We can solve the above question as
5b-4=2b+17
5b-2b=17+4 (taking like terms together)
3b=21
b=21/3
b=7
Hence the value of b is 7
1) The answer is B, 2) the answer is D, method just put all points and get know the graph of each quadrilateral
3) the measure of one angle in a regular n-gon is given by the following main formula measure of interior angle= (n-2)*180°/n,
so for n=16, we have 14*180°/16=157.5°
4) the answer is A, because 360/5=72 > 40=360/9
