First you convert the whole number into a fraction. Since you already have a fraction of 5/16, convert 2 into 16th's, which would be 32/16. Add 5/16 to 32/16 and you have 37/16. Divide 16 into 37, and your result will be a decimal. Your final answer will be 2.3125. I hope this helps!
The first one is correct because the form is y-y1=m(x-x1)
Answer:
a = 16
Step-by-step explanation:
inversely proportional
y = k/x
a = k/b
5 = k/4
solve for k
multiply by 4 on each side
20 =k
a = 20b
if b = 4/5
a = 20 * 4/5
a = 16
