First we multiply 2r*r and it gives us

.
Then -5r, + 20r = 15r
Then -5*10 gives us -50.
So the answer is:
Answer:
p=25
Step-by-step explanation:
-5[-9=-
-4] Get rid of the fraction by multiplying the whole equation by -5.
45=p+20 Then, subtract 20 from both sides.
25=p
Answer:
76.208
Step-by-step explanation:
A thousandth is 1/1000, or 0.001.

76 + 0.208 = 76.208
Note that 76,208 with a comma is wrong as it refers to seventy-six thousand, two hundred and eight.
Reducing the fractions, it is also true that:
Part A = 5/14 of the whole
Part B = 9/14 of the whole
