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

How do you answer these questions?
Maurinko [17]

Answer:

35) 5/12 36) 7/11

Step-by-step explanation:

Because, when you are drawing a girls name from the hat, the probability would be 7/12, then you replace her name and that would make the probability to draw a boys name 5/12. (since you replaced the girls name before.

now you have a probability of drawing 5/12 for a boys name, and now you don't replace the name, so the probability to draw a girls name out of the hat, would be 7/11

(idk if you have to put both answers on one, so if so, then do that for your answer Example: for 35, if the answer is 5/12, 7/12 then do that

Hope this helped, sorry I am not good at explaining things:)

Find the value of k. the diagram is not to scale
Nesterboy [21]
Given:
<span>∠SRT ≅ ∠STR, 
m∠SRT = 20, 
m∠STU = 4x

Since </span>∠SRT ≅ ∠STR,  then m∠STR = 20.

m∠STR + m∠STU = 180°
20 + 4x = 180
4x = 180 - 20
4x = 160
4x/4 = 160/4
x = 40

The value of x is 40.



I hope this is what you're looking for.
