Answer:
-0.4x - 0.30 or 
Step-by-step explanation:
Change all the fractions to decimals.
-2/5 = -0.4 Distribute that over x and 0.8 1/50 = 0.02
you get -0.4x -0.32 + 0.02
Change all the decimals to fractions.
0.8 is 8/10 so -2/5 times 8/10 is -16/50
-2x/5 - 16/50 + 1/50 add or subtract the fractions to get -15/50 Then reduce (÷5)
-2x/5 - 3/10

Answer:
Step-by-step explanation:
Volume= (length)(width)(height)
step 1: make sure all the measurements have the same unit (ft)
step 2: convert mixed fractions to improper fractions
1 2/3= 5/3 1 1/6= 7/6 1 1/5 = 6/5
multiply the length by width and height
(5/3)(7/6)(6/5)
=7/3 ft^3

Follow the reasoning.
288 ÷ 2 = 144
and 144 its a perfect square (144 = 12²)
It is visible that if we multiply 288 by 1/2, we will obtain a perfect square, but we will do this via a simple equation
288 · X = 144
X = 144 ÷ 288
X = 0,5 ⇔ X = 1/2
