3/4 would be a fraction, equivalent to 6/8.
Move all the x terms to one side and solve for x. 15x-10x=21-6 : 5x/5=15/5 : x=3
Step 1
<u>Find the value of x</u>
we know that
-------> by corresponding angles, because the given lines are parallel
Solve for x

Step 2
<u>Find the value of y</u>
we know that

substitute the value of x and solve for y





therefore
<u>the answer is the option B</u>

20x(5/100)=1
That is the interest after one year
Add to the principal:20+1=21
The difference between the 2 5s is that the 50,000 is 10 x bigger than the 5000 five.
Hope this helps:)
