To find x you need to make the variable alone:

subtract three from the right side, 15-3=-2x, simplify

12=-2x, then divide by negative 2

x=(-6)

A party is thrown where 25 tables are used. Each table either sits 4 people or 6 people. A total of 116 people can be sat at the

Soloha48 [4]

Answer:

(a) 4 y + 6 s = 116 represents the given situation.

(b)There are 8 six- person tables at the party.

Step-by-step explanation:

Here, the total number of tables = 25

Let y : Represent the number of four person tables.

s : Represents the number of six person tables.

Total people seated at all tables = 116

Now, the number of people seated at table of 4 = y x 4 = 4 y

the number of people seated at table of 6 = s x 6 = 6 s

(a) Total People Seated = People seated at { 4- table + 6 table}

⇒ 116 = 4 y + 6 s

Hence, 4 y + 6 s = 116 represents the given situation.

(b) Total tables are 25. ⇒ s + y = 25

Hence, the givens system of equations are:

4 y + 6 s = 116 ........ (1)

s + y = 25 ............ (2)

Solving the above system, we get, substitute y = 25 - s in (1)

4 y + 6 s = 116 ⇒ 4(25-s) + 6s = 116

or, 100 - 4s + 6s = 116

or. 2s = 16

or, s = 16 / 2 = 8 ⇒ s = 8

Hence, there are 8 six- person tables at the party.

Its not telling me how to do this, please help

kenny6666 [7]

Step-by-step explanation:

Actually, it tells you exactly what to do.

First, translate, i.e., move over, the coordinates up by 3:

$(1, 4)\rightarrow (1+3, 4+3) = (4, 7)$

Then reflect this point about the x-axis and to do this,

$(x, y) \rightarrow (x, -y)$

$(4, 7) \rightarrow (4, -7)$

Which expression could represent the length of a rectangle that has an area equal to 4x2+12x?

grandymaker [24]

there are two expressions that can represent the length of the rectangle, these two expressions are:

L = x

L = (4x + 12)

<h3>Which expression could represent the length of the rectangle?</h3>

Remember that for a rectangle of length L and width W, the area is given by:

A = L*W

In this case, we know that the area is:

$A = 4x^2 + 12x$

We can factorize that expression into:

$A = x*(4x + 12)$

So there are two expressions that can represent the length of the rectangle, these two expressions are:

L = x

L = (4x + 12)
