If 45% of x is 200, what is x?

Answers

Answer 1

Answer: ' 45% ' means ' 0.45 ' .
' of ' means ' times '.

0.45 times 'x' = 200

Divide each side by 0.45 : x = 200/0.45

x = 444 and 4/9 .

Answer 2

Answer: 45% of x=200
(45/100)x=200
x=(200*100) / 45=444.4444....≈444.44

Answer: x=444.44

To check
45% of 444.44=0.45 * 444.44≈200

3. Ron used 24 cubes to make this 3-step staircase. If he uses a total of 84 cubes to make a similar staircase, how many steps will the staircase have?

Answers

Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)

28 steps because 84 divided by 3 equals 28

Answer:\

x ≥ 6

Step-by-step explanation:\

4x -30≥ - 3x + 12

add 30 to bot size

4x - 30 + 30 ≥ -3x + 12 + 30

simplify

4x ≥ -3x + 42

add 3x to bot sides

4x +3x ≥ -3x+42+3x

simplify

7x ≥ 42

divide bot sides by 7

7x/7 ≥ 42/7

simplify

x ≥ 6

Explain how you would find 36 x 3/4 mentally

Answers

Ok so first what you need to do is think about the question because this is a very simple question to understand and as they say nothing in this world is easy so you have to think about it and once you think about it and understand what they are asking you then you could solve and its very simple. 1st you have to follow order of operations which PEMDAS and I think you should be familiar using this strategy because I am very accoustomed to it and you should be as well, anyway, first do multiplication because in PEMDAS the m comes before the d which stands for division. So do 36x3 which is 108 and now we could do the final step which is to divide our product, 108, by 4 and the quotient shall be 27 as our final answer. So hope this helped you out and if it did than awesome and thank you for the question by the way so keep on asking questions!!

Calculating 36 x 3/4 gives you the result of 27.

To find 36 multiplied by 3/4 mentally, you can follow these steps:

1. Simplify the fraction: 3/4 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1 in this case.

This simplification leaves us with 3/4 as the fraction.

2. Convert the whole number to a fraction:

Since 36 is a whole number, we can rewrite it as a fraction with a denominator of 1. So, 36 can be expressed as 36/1.

3. Multiply the numerators: Multiply the numerators of the fractions together: 36 x 3 = 108.

4. Multiply the denominators: Multiply the denominators of the fractions together: 1 x 4 = 4.

5. Write the result as a fraction: Take the product of the numerators and write it over the product of the denominators: 108/4.

6. Simplify the fraction if possible: Divide both the numerator and the denominator of the fraction by their greatest common divisor, which is 4 in this case. Simplifying the fraction gives us 27/1 or simply 27.

Therefore, mentally calculating 36 x 3/4 gives you the result of 27.
