Answer:

Step-by-step explanation:

5.40/12

Answer:

3/5

Step-by-step explanation:

Let x be the numerator

Let y be the denominator

1st equation:

(x-1) / (y-1) = 1/2

By simplifying the equation, 2(x-1) = y-1

y = 2(x-1) + 1

2nd equation:

(x+1) / (y+1) = 2/3

By simplifying the equation, 3(x+1) = 2(y+1)

3x + 3 = 2y + 2

2y = 3x + 1

y = (3x + 1) / 2

Substituting the value of y from the 1st equation to the 2nd equation:

1st equation: y = 2(x-1) + 1

2nd equation: y = (3x + 1) / 2

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

x = 3

After finding the value of x, let's find y using the 2nd equation:

y = (3x + 1) / 2

y = [(3)(3) + 1] / 2

y = 5

Alternatively, we may also find the value of x using the first equation, and the result is still the same:

y = 2(x-1) + 1

y = 2(3-1) + 1

y = 5

CHECKING TIME!!!

Substituting the values of x and y:

Let x be the numerator, x = 3

Let y be the denominator, y = 5

1st equation: (x-1) / (y-1) = 1/2

(3-1) / (5-1) = 1/2

2/4 = 1/2

By simplification, 1/2 = 1/2

2nd equation:

(x+1) / (y+1) = 2/3

(3+1) / (5+1) = 2/3

4/6 = 2/3

By simplification, 2/3 = 2/3

To make the same orange circle, you would need 2:3 drops of food coloring.

A ratio is a mathematical statement that compares and equals two variables.

Fractions, percentages, and decimals are used to represent ratios.

According to this ratio (2:3), Maia uses 60% of yellow food coloring to create an orange circle for every 40% of red food coloring.

Information and calculations: 4 red food coloring drops

Yellow food coloring drops equal six.

Food coloring ratio = 4:6 or 2:3.

The ratios are as follows in percentages:

Red food coloring drops equal 40% (2/5 x 100)

60 (3/5 x 100) drops of yellow food coloring

As a result, the food coloring is divided into 40% red and 60% yellow.

Answer:

16 children would be left out in this arrangement​

Step-by-step explanation:

Total number of children in a school = 500

For P.T. Drill number of rows = number of columns =x

The number of children who will be left out = 500−x^2  .

The square root of 500 gives remainder as 16 that means, the square of 22 is less than 500 by 16

To make it a perfect square = 500−16=484 Therefore, number of children left will be 16

= 16 children would be left out in this arrangement​

Answer:

h(-4) = -1

h(-1) = -1

h(0) = 2

Step-by-step explanation:

h(-4) = -1 because -4<-1 and from the instructions if x < -1, it is -1

h(-1) = -1 because -1 = -1

h(0) = 2 because if 1<x<2 than we have to solute this -(x-1)^2 + 3

in this we have to replace x with 0

-(0-1)^2 + 3= -(-1)^2 + 3 = -1 +3 = 2

Answer:

$5 per pound of grapes

Step-by-step explanation:

Because 2/5 a pound of grapes cost $2 you would add another $2 for 4/5 pound of grapes. Then, you would divide 2 by 1/2 to get $1.

So 1 pound of grapes = $5

Hope this helps!!    **please give me brainliest :)

The cost of per pound of grapes is $5.

A number juggling activity is determined by consolidating operands with one math administrator. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations.

Both the plus sign and the minus sign can be used as operators with prefixes or infixes. Only infix operators can be used to represent all other arithmetic operators.

Given cost of 2/5 pound of grapes is $2

2/5p = 2

where p = pound

p = (2 x 5)/2

1p = 5

1 pound = $5

Therefore the 1 pound of grapes cost $5.
