Hillary buys 3 pounds of Gala apples and some Granny Smith apples. Both kinds of apples cost $4.50 per pound. The total cost is

Elodia [21]

Answer:

24.75 = 3*4.50 + x*4.50

x= 2.5 pounds of Granny Smith apples

Step-by-step explanation:

Gala apples = 3 lbs

Granny apples = x lbs

They cost 4.50 a pound

Total cost = 24.75

Total cost = gala apples * cost per pound + granny apples * cost per pound

Substitute in what we know

24.75 = 3*4.50 + x*4.50

24.75 = 13.50 + 4.5x

Subtract 13.50 from each side

24.75-13.50 = 13.50-13.50 + 4.5x

11.25 = 4.5x

Divide by 4.50 on each side

11.25/4.5 = 4.5x/4.5

2.5 =x

The area of this rectangle is 54 square inches. Create an equation to find the value of n. Length is 3(n-1) and the width is n+2

olasank [31]

Value of n is 4

The area of a rectangle is equal to the product of its length and width.

we know ,

the area of rectangle, multiply the length, , and the width, ,

and set the product equal to the area.

area of rectangle = length * width

54 = 3(n - 1) * (n + 2)

54 =( 3n - 3) * (n + 2)

multiply ( 3n - 3) with (n + 2)

we get,

54 = $3n^{2} + 6n - 3n -6$

54 = $3n^{2} + 3n -6$

54 = 3( $n^{2} + n -2$ )

$\frac{54}{3}$ = ( $n^{2} + n -2$ )

18 = ( $n^{2} + n - 2$ )

$n^{2} + n - 2$ - 18 = 0

$n^{2} + n - 20$ = 0

solve them

$n^{2} + 5n + 4n -20$ = 0

n (n + 5) - 4 (n + 5) = 0

(n + 5)(n -4)

then we get,

n = -5 , n = 4

value of n should not be negative . so value of n is 4

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.

The area of a rectangle depends on its sides. Basically, the formula for area is equal to the product of length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides. Hence, we can say, the region enclosed by the perimeter of the rectangle is its area

Area of rectangle = Length x Breadth

A = lb

how to Factoring Quadratic Equation

Step 1: Consider the quadratic equation ax2 + b x + c = 0

Step 2: Now, find two numbers such that their product is equal to ac and sum equals to b.

(number 1)(number 2) = ac

(number 1) + (number 2) = b

Step 3: Substitute these two numbers in the formula given below:

(1/a) [a x + (number 1)] [a x + (number 2)] = 0

Step 4: Finally simplify the above equation.
