An equation is shown below: 4c + 2(x-3) = 4x + 2x - 11 Part A: solve the equation and write the number of solutions. Show all the steps. Part B: Name one property you used to solve this equation.

Answers

Part A: first multiply 2 by x and -3 → combine all like terms → Add 6 on both sides → subtract 6x from both sides.

Your final answer should be -5

step by step: 4x + 2(x-3) = 4x + 2x - 11

4x +2x -6 = 4x + 2x - 11

6x -6 = 6x - 11

6x = 6x -11 +6

6x = 6x -5

6x-6x= -5

0 = -5

Part B: Add all like terms.

Hope this helps! :)

There is NO SOLUTION. We used the distributive property to distribute the 2(x-3).

Explanation:
4x+2(x-3)=4x+2x-11
4x+2x-6=4x+2x-11 Distribute 2 by x-3
6x-6=6x-11 Combine Like Terms
-6=-11 Subtract Weaker X
-6≠-11 Find Answer

-6 does not equal -11, so there is no solution to this equation.

A store sells two kinds of candles,scented candles and unscented candles. The candles burn at different rates which kind of candle burns more in one hour? How much more per hour? The scented one burns 1/8inch an hour 1/4 hour and the unscented one burns 1/9 inch in 1/3 hour. SHOW WORK!!!!

Answers

Step-by-step explanation:

The first thing we must observe is that the hourly rate for each candle is:

scented candles:

(1/12) / (20/60)

Simplifying:

= (1/12) / (10/30)

= (1/12) / (5/15)

= (1/12) / (1/3)

= (3/12)

= (1/4) inches / hour

Unscented candles:

(1/6) / (30/60)

Simplifying:

= (1/6) / (15/30)

= (1/6) / (3/6)

= (1/6) / (1/2)

= (2/6)

= (1/3) inches / hour

Answer:

The unscented candles burn faster at a rate of:

(1/3) inches / hour.

Answer:

You look at the numbers

Step-by-step explanation:

1/8inch per hour

Answer:

1 inch represents 1/3 foot

Step-by-step explanation:

Scale = 51 inches

Actual = 17 feet or 204 inches

Use a ratio to compare the two 204:51 or 204/51 = 4

This means that the actual size is 4 times the scale size

Take 1 inch in the scaled size and multiply it by 4 to get the actual size to get 4 inches

4 inches = 1/3 foot, therefore 1 inch represents 1/3 foot

Answers

Answer:

I'd say, the more thrust it has the longer its trajectory will be.

Step-by-step explanation:

Answer:

The relative magnitude and direction of the forces determines the flight trajectory of the rocket. At launch, the thrust of the rocket engine is greater than the weight of the rocket and the net force accelerates the rocket away from the pad. Unlike full scale rockets, model rockets rely on aerodynamics for stability. I hope that helps.
