24 is 40% of what number? Use the percent equation.

Answers

Divide 24 by 40%

24 / 0.40 = 60

The answer is 60

Using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).

What is Percentage?

Percentage is simply number or ratio expressed as a fraction of 100.

The perecent equation is expressed as;

Percentage = ( Part / Whole ) × 100%

Given the data in the question;

Percentage = 40%Part = 24Whole = ?

We determine the number, we substitute our given values into the expression above.

Percentage = ( Part / Whole ) × 100%

40% = ( 24 / Whole ) × 100%

40/100 = ( 24 / Whole ) × 100/100

40/100 = 24 / Whole

We cross multiply

40 × Whole = 24 × 100

40 × Whole = 2400

Whole = 2400 / 40

Whole = 60

Therefore, using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).

The equation given was: (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87.

Using this equation, write the equation with fewer terms.

Answers

Answer:

x = 13

Step-by-step explanation:

(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87

x + x + 3 + x - 2 + 3x + 9 - 1 = 87

6x + 9 = 87

6x = 87 - 9

6x = 78

x = 78/6

x = 13

(Distribute)

2x+−5=5x+−2

2x−5=5x−2

Step 2: Subtract 5x from both sides.

2x−5−5x=5x−2−5x

−3x−5=−2

Step 3: Add 5 to both sides.

−3x−5+5=−2+5

−3x=3

Step 4: Divide both sides by -3.

X= -12 -6y, Y= -2- x/6

Step-by-step explanation:

For x

-2x-12y=24

-2x/-2 -12y/-2. 24/-2. Divide all by -2

X+6y=-12 this is what you get after

-6y. -6y. Subtract from both sides

X=-12-6y this is what you get

Find y

-2x-12y=24

-2/-2. -12/-2. 24/-2

X -6y=-12

-x. -x

-6y=-12-x

-6y/-6. -12/-6. -x/-6

Y = -2 - x/6

First for x substitute y for zero then for x substitute y for zero ; if you need to graph then take a glance at my picture. Good Luck!

What is Number system?

A number system is defined as a system of writing to express numbers.

Given that the cost of 4 bananas is $2.36

We have to find the cost of each banana.

To find this we have to divide the cost by number of bananas

Divide two point three six by four

Banana is denoted by b

4b=$2.36 is the required equation

Cost of each banana =$2.36/4

=$0.59
