Answer:

The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch

Step-by-step explanation:

Let

x ----> the number of bags of hardwood mulch sold

y ----> the number of bags of pine bark mulch sold

we know that

A local boys club sold 136 bags of mulch and made a total of $400

$x+y=136$ ----> equation A

$3.25x+2.75y=400$ ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

Using a graphing tool

The solution is the point (52,84)

see the attached figure

therefore

The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch

If the area of a rectangle in terms of x is x2 + 15x + 26 / 6x2 and its width is x2 - 3x - 10 / 30x3 Find the length of the rect

Veseljchak [2.6K]

Answer:

The length of the rectangle is;

5x(x+13)/(x-5)

Step-by-step explanation:

Mathematically, we know that the area of a rectangle is the product of the length and width of the triangle

To find the length of the rectangle, we will have to divide the area by the width

we have this as;

(x^2 + 15x + 26)/6x^2 divided by (x^2-3x-10)/30x^3

thus, we have ;

(x^2 + 15x + 26)/6x^2 * 30x^3/(x^2-3x-10)

= (x^2+15x+ 26)/(x^2-3x-10) * 5x

But;

(x^2 + 15x + 26) = (x+ 2)(x+ 13)

(x^2-3x-10) = (x+2)(x-5)

Substituting the linear products in place of the trinomials, we have;

(x+2)(x+13)/(x+2)(x-5) * 5x

= 5x(x+13)/(x-5)

Let's solve ~

$\qquad \sf \dashrightarrow \: \cfrac{1}{b} + 10 = \cfrac{9}{b} + 7$

$\qquad \sf \dashrightarrow \: \cfrac{9}{b} - \cfrac{1}{b} = 10 - 7$

$\qquad \sf \dashrightarrow \: \cfrac{8}{b} = 3$

$\qquad \sf \dashrightarrow \: b = \cfrac{8}{3}$

The area of a square piece of cardboard is 81 square inches. What is the length of the cardboard?

Marianna [84]

Answer:

Step-by-step explanation:

The area of a square is found in the formula

$A=s^2$

We have the Area value so we will plug it in:

$81=s^2$

Take the square root of both sides to undo the square on the s to get that

s = 9
