Answer:
3 1/8 or 3.125.
Step-by-step explanation:
First you would change 1 1/4 to 5/4. Then you would make a proportion of 5/4 or I like to use decimals, 1.25, over 8. Your proportion would look like: 1.25/8 = x/20. Then cross multiply 1.25 and 20 then divide your product by 8. Your final answer is 3.125 or 3 1/8. Hope this helps!

Answer:
Gradient of the line with points (-4,1)&(3,-2) is
(-2-1)÷(3-(-4))=-3/7
Then the equation of that^ line is
Y-1=-3/7(x-(-4))--->y=-3/7x-5/7
Since this^ line is perpendicular to the line you are looking for.the gradient of the line you are looking for is -1÷(-3/7)=7/3
The equation of the line you are looking for is
Y-1=7/3(x-2)--->y=7/3x-11/3
[Cause the line you are looking for passes through the point (2,1) and you found the gradient of this line]
to get t alone you need to divide it by pr
when you do that you also need to divide I by pr
so t = i/pr
