<h2>Approximately 4824 games </h2>

Step-by-step explanation:

Given that the sales made are 4,567 ,5430, 3998, 5,220,and 4,906

the average is (4567+5430+3998+5220+4906)/5

=24121/5

=4824.2

in the month of august let the sales be x

average= (4567+5430+3998+5220+4906+x)/6

the average for march to july is 4824.2

4824.2= (4567+5430+3998+5220+4906+x)/6

24121+x=4824.2*6

24121+x=28945.2

x=28945.2-24121

x=4824.2

approximately 4824 games

Can I get some help? I don’t understand this :/

DIA [1.3K]

Together they equal 90 degrees.
Equation:
(0.1x - 22) + (0.3x - 54) = 90
Open parenthesis and simplify:
0.4x -76 = 90
0.4x = 166
DIvide:
Your final answer is x= 415
Hope this helps!

A florist sells a bouquet of roses

NikAS [45]

Answer:

Bouquets of roses = 20

Bouquets of carnations = 08

Step-by-step explanation:

Let,

x be the bouquets of roses sold

y be the bouquets of carnations sold

According to given statement;

x + y = 28 Eqn 1

16x + 10y = 400 Eqn 2

Multiplying Eqn 1 by 16

16(x+y=28)

16x + 16y = 448 Eqn 3

Subtracting Eqn 2 from Eqn 3

(16x+16y)-(16x+10y) = 448 - 400

16x + 16y - 16x - 10y = 48

6y = 48

Dividing both sides by 6

$\frac{6y}{6}=\frac{48}{6}\\y=8$

Putting y=8 in Eqn 1

x + 8 = 28

x = 28 - 8

x= 20

Hence,

Bouquets of roses = 20

Bouquets of carnations = 08

Point A has coordinates (6,4) and point B has coordinates (2,7) write AB as column vector. Plz plz plz

Olenka [21]

Answer:

$\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}$

Step-by-step explanation:

<u>Column Vector</u>

Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.

It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).

The vector directed from A to B is found by subtracting its corresponding coordinates:

$\overrightarrow{AB }=$

Now we express the vector as a one-column matrix as follows:

$\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}$
