I'm assuming that the side AE is *1.5 of BF. (I havent learnt about midpoints, but I know it's the middle)
23*1.5=<span>34.5
</span>
5x-4=34.5+4 on both sides
5x=38.5/5 on both sidesx=<span>7.7</span>
44 Stamps. 5.55/0.15 = 37 stamps. 37 + 7 = 44. 44 Stamps.
Answer:
Step-by-step explanation:
1
2
is equivalent to 6
12
because 1 x 12 = 2 x 6 = 12
2
4
is equivalent to 6
12
because 2 x 12 = 4 x 6 = 24
3
6
is equivalent to 6
12
because 3 x 12 = 6 x 6 = 36
4
8
is equivalent to 6
12
because 4 x 12 = 8 x 6 = 48
Its C.125 is the correct answer...
Sec(x/2) = 1/cos(x/2)
sec(x/2)=cos(x/2) ----> cos^2(x/2)=1 ---> cos(x/2) = -1 and cos(x/2) = 1
Cos(x/2)=1 --- > x/2 = 0, only. x = 0;
cos(x/2)=-1 ----> x/2 = pi -> x = 2pi. But the statement says [0,2pi), so 2pi can not be chosen.
Only x = 0.
In fact, your equation is equivalent to sec(x)=cos(x), for x in [ 0, pi), so yes, only x = 0 .
