Answer: 1/30x (381x+10y)


Explanation:

(4x + 2/3y) - (4/12y - 8.7x) = 12.7x+1/3y

Convert 12.7x in the difference to a fraction, which is 127/10x.

Factor out 1/30 from 127/10x + 1/3y


Solution: 1/30x (381x+10y)


12.7x+1/3y

Solve the following equation and then graphically: 16x + =14x + 10
cestrela7 [59]

Answer:

Step-by-step explanation:

Simplifying

16x + -14 = 14x + -10

Reorder the terms:

-14 + 16x = 14x + -10

Reorder the terms:

-14 + 16x = -10 + 14x

Solving

-14 + 16x = -10 + 14x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14x' to each side of the equation.

-14 + 16x + -14x = -10 + 14x + -14x

Combine like terms: 16x + -14x = 2x

-14 + 2x = -10 + 14x + -14x

Combine like terms: 14x + -14x = 0

-14 + 2x = -10 + 0

-14 + 2x = -10

Add '14' to each side of the equation.

-14 + 14 + 2x = -10 + 14

Combine like terms: -14 + 14 = 0

0 + 2x = -10 + 14

2x = -10 + 14

Combine like terms: -10 + 14 = 4

2x = 4

Divide each side by '2'.

x = 2 Simplifying

16x + -14 = 14x + -10

Reorder the terms:

-14 + 16x = 14x + -10

Reorder the terms:

-14 + 16x = -10 + 14x

Solving

-14 + 16x = -10 + 14x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14x' to each side of the equation.

-14 + 16x + -14x = -10 + 14x + -14x

Combine like terms: 16x + -14x = 2x

-14 + 2x = -10 + 14x + -14x

Combine like terms: 14x + -14x = 0

-14 + 2x = -10 + 0

-14 + 2x = -10

Add '14' to each side of the equation.

-14 + 14 + 2x = -10 + 14

Combine like terms: -14 + 14 = 0

0 + 2x = -10 + 14

2x = -10 + 14

Combine like terms: -10 + 14 = 4

2x = 4

Divide each side by '2'.

x = 2

Simplifying

x = 2

Simplifying

x = 2

Drag the amounts to order them from greatest to least.
Komok [63]

So, problem statement tells you that 1lb = 16oz and that 1oz = 28.3g. That means that 1lb = 16 * 28.3g = 452.8g


You have three items, convert their weights to grams:

1) 800g

2) 1.6lb = 1.6 * 452.8g = 724.48g

3) 30oz = 30 * 28.3g = 849g


So, sorting from greatest:

3, 2, 1, or: 30oz, 1.6lb, 800g.


Hope this helped.
