Step-by-step explanation:
1634*0.97*1.04
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

good luck :)
The total weight is 2 1/2 lbs
Rock A is 1/7 of the total weight....so it is 1/7 of 2 1/2 lbs..." of " means multiply
1/7 * 2 1/2 =
1/7 * 5/2 =
5/14 lbs <==
