x - 2y = 8 then it is y = 0.5x-4.
Hope I helped! ( Smiles )
Answer:
its the 3rd choice.
Step-by-step explanation:
Firstly, we find angle BDC (180-90-30=60)
Now that we found it we can use the sine rule to find DB (which i put as an x), which is sin60/14=sin30/x, by cross multiplication, we find that its equal to a decimal number, i will use its root version to this easier, its equal to 14sqrt3/3 inches.
And now we use the pythagorean theorem to find DC, we find that it is equal to 28sqrt3/3
Now, we find angle BAC (180-90-(30+15)=45)
Again, we use the sine rule to find AB (whom i will refer to as x and from whom we will subtract DB to find the length of AD), so we cross multiply in sin45/14=sin(30+15)/x, it is equal to 14.
So since AB-DC=AD
14-(14sqrt3/3)= 5.917096231 (and we ound that to a 5.9)
The first thing we must do for this case is to define variables.
We have then:
x = number of dimes
y = number of half-dollars
We write the system of equations:
x + y = 36
0.10x + 0.50y = 12
Solving the system we have:
x = 15
y = 21
Answer:
He has 15 dimes
<h3><u>Given</u>:-</h3>
