It should be either the last one or the first one but it will probably be the last one.
Answer:
$26.31
Step-by-step explanation:
Since 3 is half of 6, 3 pairs of shoes would cost half the price.
So...
52.62/2=$26.31
Answer:
6
Step-by-step explanation:
14x+21+6=12x+39
14x+27=12x+39
14x-12x=39-27
2x=12
x=6
Answer:
123.46 or 42.28
Step-by-step explanation:
Assuming that b is the leg side of a triangle and that c is the hypotenuse, we can solve for c using SOHCAHTOA.
We can find the angle from the equation sin X = 0.3240.
X =
0.3240
X = ...
Through SOHCAHTOA, we know that we should use either sin X =
or that cos X =
.
I'm going to assume that we use sin X =
since we are given a length b and not a length a. So:
sin 18.9050 = 
c =
= 123.46
If we use cos X =
, then:
cos 18.9050 = 
c =
= 42.28
Not sure which one is correct since we are not given a picture of the sides.
