First you make the fractions top heavy instead of mixed numbers, so:
5/2 × 16/5
Then you just multiply across:
5 × 16 = 80
2 × 5 = 10
Your answer is 80/10, which can be simplified to 8.
Answer:
f(3)=11
Step-by-step explanation:
f(x) = 2x + 5
to find f(3) we simply plug in 3 where ever x is
So f(3) = 2(3) + 5
==> multiply 2 and 3
f(3) = 6 + 5
==> add 6 and 6
f(3) = 11
Answer:
c
Step-by-step explanation:
right
Move the decimal place one point to the right
Example 3.75 x 10 = 37.5
-- 9 people paint 5 walls in 60 minutes
-- 9 people paint (5 / 5) = 1 wall in (60 / 5) = 12 minutes
-- (9 / 9) = 1 person paints 1 wall in (9 x 12) = 108 minutes
-- 1 person paints (1 x 6) = 6 walls in (108 x 6) = 648 minutes
-- (1 x 4) = 4 people paint 6 walls in (648 / 4) = 162 minutes .
