7x+y=11 where y= -5                                                                                              So, when we substitute y in the equation then,
7x + (-5) = 11 that is 7x - 5 = 11....
So, B. is the right answer.

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 4.5\text{ m}^34.5 m 3 4, point, 5, start t
Vika [28.1K]

Answer:

2 meters

Step-by-step explanation:

Given

Volume = 4.5m^3

The question is incomplete as the picture of the tent is not attached.

However, I will use the attached figure to answer the question.

From the attachment, we have:

b = 1.5m --- base of the tent

l = 3m --- length of the tent

Required

Determine the height of the tent

The volume of the tent is:

\frac{1}{2} * bhl = Volume

Where h is the required height.

So, we have:

\frac{1}{2} * 1.5 * h * 3 = 4.5

\frac{1}{2} * 1.5 * 3 * h = 4.5

\frac{1}{2} * 4.5 * h = 4.5

Make h the subject

h = \frac{4.5 * 2}{4.5}

h = 2m

<em>The height of the tent is 2m</em>

So what if the area is 7200 sq m and side is 80 m . Pls help
Basile [38]

Hello,

If it is a rectangular field, then to find the other dimension (x), divide the area (A) by the other dimension (y).

x = a / y

x = 7 200 m² / 80 m = 90 cm

Bye :)
