X equals 1 because you would add 1/2 to the other side to get x alone and then divide by 1/4 to leave x completely alone

-4-3 (6x + 9) = 41?<br> Explain what to do first and what is the answer
lara31 [8.8K]

Answer:

x = -2

Step-by-step explanation:

- 3 x - 6x = -18x

- 4 - 18x + 9 = 41

9 - 4 = 5

- 18x + 5 = 41

- 18x = 41 - 5

- 18x = 36

36 divided by -18 is -2

How many bananas are needed to make the third scale balance?
frozen [14]

The number of bananas required to make the third scale balance is 3.

<h3>What is a scale?</h3>

A scale is a tool used for weighting objects. If the objects on each side weigh the same the scale is balanced. Based on this, let's determine the possible weight of each fruit to balance the last scale.

  • Scale 1 (10 bananas/ 2 pineapples)

It is known 10 bananas weigh as much as 2 apples, but to solve this problem let's assume 10 bananas weigh a total of 1000 grams.

  • 10 banans = 1000 grams = each banana weighs 100 grams
  • 2 pineapples =  1000 grams = each pineapple weighs 500 grams

Scale 2 ( 1 pineapple / 2 bananas, 1 apple)

Using the same imaginary weights let's find the weight of the apple.

  • 1 pineapple = 500 grams
  • 2 bananas = 200 grams
  • 1 apple = 300 grams (500 - 200 = 300)

Scale 3 (1 apple /x )

We know 1 apple is equal to 300 grams and 1 banana is equal to 100 grams. Based on this, the number of bananas to balance the scale is 3.

Whats an equation that make x=31 ? like in other words give me an equation where it leads down to 31
MrRa [10]
Sure, that's easy! Here's one

5x + 7 = 162

If I wanted to solve this equation, I would break it down. I'd subtract the result (162) by 7

162 - 7 = 155.

From there I just divide that by 5!

155 / 5 = 31

There it is! Ultimate proof that x is in fact 31!
