<span>We can say that 20 students represent 100 % and that 4 students represent x % of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 % Answer: 4 students is 20 % of 20 students. Hope this helps. Let me know if you need additional help!</span>
Answer:
4 1/3 miles = 13/3 miles
Step-by-step explanation:
One way to add these mixed numbers is to convert them to improper fractions with a common denominator.
(1 5/6) + (2 1/2) = 11/6 + 15/6
= (11 +15)/6 = 26/6 = 13/3 . . . . (a fraction)
= 4 1/3 . . . . (a mixed number)
Hello :)
They are basically asking which one of these expansion would give you the right answer.
So first you would have to solve the expression, by using foil.
(4x+1)(2x^2-2)
F- first
4x · 2x^2
O- outer
+4x · (-2)
I- inner
+1 · 2x^2
L- last
Put all of the expressions together.
the answer would be A
The answer is B hope it helps :)
