4 because 40 divid 2= 20 ,40 divid 4=10 ,40 divid 8=5, 40 divid 12=36 remainder 4 remainder =what is left
Answer:
You need to simplify 0.3(12x + -16) = 0.4(12 + -3x)
Step-by-step explanation:
Reorder the terms:
0.3(-16 + 12x) = 0.4(12 + -3x) (-16 * 0.3 + 12x * 0.3) = 0.4(12 + -3x) (-4.8 + 3.6x) = 0.4(12 + -3x) -4.8 + 3.6x = (12 * 0.4 + -3x * 0.4) -4.8 + 3.6x = (4.8 + -1.2x)
Solving -4.8 + 3.6x = 4.8 + -1.2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.2x' to each side of the equation. -4.8 + 3.6x + 1.2x = 4.8 + -1.2x + 1.2x
Combine like terms: 3.6x + 1.2x = 4.8x -4.8 + 4.8x = 4.8 + -1.2x + 1.2x
Combine like terms: -1.2x + 1.2x = 0.0 -4.8 + 4.8x = 4.8 + 0.0 -4.8 + 4.8x = 4.8 Add '4.8' to each side of the equation. -4.8 + 4.8 + 4.8x = 4.8 + 4.8
Combine like terms: -4.8 + 4.8 = 0.0 0.0 + 4.8x = 4.8 + 4.8 4.8x = 4.8 + 4.8
Combine like terms: 4.8 + 4.8 = 9.6 4.8x = 9.6 Divide each side by '4.8'. x = 2
Simplifying x = 2
18/4=4.5 so you can have 4 groups with a group of 2
I hope this helps:)
