Answer:

Perimeter= 84

Area= 360

Step-by-step explanation:

We know that this field has portions split up by 7. The length is 5/7 of that, and the width is 2/7.

We know that the length is 30yd. 30/42 is the equivalent of 5/7. That means that 12/42 is the equivalent of 2/7.

Thus, the width of the field is equal to 12.

To find the perimeter we will add all sides. 30 + 30 + 12 + 12 = 84

We will multiply them to find area. 30 * 12 = 360

Answer:

(b) x +2y = 8

Step-by-step explanation:

The only offered line that includes the given point is ...

x +2y = 8

We can check the other choices:

x + 2y = 2 +2(3) = 2+6 = 8 . . . matches B (not A)

2x +y = 2(2) +3 = 4+3 = 7 . . . . not a choice

_____

<em>Getting there from scratch</em>

The standard form equation for a line can be written from ...

(y2 -y1)x -(x2 -x1)y = constant

(-4 -0)x -(4 -(-4))y = constant . . . . using the given points (-4, 0) and (4, -4)

-4x -8y = constant

For standard form, we need the leading coefficient to be positive, and we need common factors removed. We can get there by dividing by -4.

x +2y = constant

The value of the constant will be whatever it takes for the given point to lie on the line. For (x, y) = (2, 3) to be a solution, we must have ...

x +2y = (2) +2(3) = constant = 8

The desired line has the equation ...

x +2y = 8

exis [7]

Answer:

2 bags of topsoil.

Step-by-step explanation:

The attached figure shows a flower bed.

One bag of topsoil covers 15 square meters.

We need to find how many bags of topsoil does Tom need to cover his flower bed.

The area of the flower bed is :

$A=\dfrac{1}{2}\times 12\times 5\\\\=30\ m^2$

Let he has to cover x bags of topsoil. So,

x = Area of flower bed/Area of 1 bag of top soil

x = 30/15

x = 2

Hence, he will need 2 bags of topsoil to cover his flower bed.

Answer:

$2+2-1-1+6=x : x = 8$

Step-by-step explanation:

$2+2-1-1+6=x\\$

Switch sides:

$x=2+2-1-1+6$

Add/Subtract the numbers: $2+2-1-1+6=8$

$x = 8$

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)
