Answer:

10.6

Step-by-step explanation:

A rhombus has equal length sides

6x-11 = 25 -4x

Add 4x to each side

6x-11+4x = 25-4x+4x

10x-11 = 25

Add 11 to each side

10x +11-11 = 25 +11

10x = 36

Divide by 10

10x/10 = 36/10

x = 3.6

Now we need to find the length of a side (since they are equal)

6x-11

6(3.6) -11

21.6-11

10.6

since it's rhombus, then

6x-11=25-4x

10x=36

x=3.6

each side = 25-4(3.6)

= 25 - 14.4

= 10.6

Graph f(x)=3x+5 and g(x)=3x-2
IgorLugansk [536]

Answer:

Two parallel lines

Step-by-step explanation:

the slopes are the same: slope = 3

f(x) 3x + 5                          g(x) = 3x - 2

Pick at least three x values and find their corresponding values for y. Remember the f(x)  and g(x) represent y

                                   f(x) = 3x + 5                           g(x) = 3x - 2

                                    y = 3x + 5                              y = 3x - 2

let x = 0                       y = 3(0) + 5                              y = 3(0) - 2

                                     y = 5                                         y   =  -2

Ordered pair                (0, 5)                                        (0, -2)

Let x = 1                      y = 3(1) +5                                y  = 3(1) - 2

                                  y = 8                                         y = 1

ordered pair                (1, 8)                                        (1, 1)

Let x = -1                  y = 3(-1) + 5                               y = 3(-1) - 2                  

                                  y = 2                                        y =  -5

ordered pair             (-1, 2)                                         ( -1, -5)

Locate the ordered pairs and draw the graph on the lines.  

you will graph two parallel lines

Answer:

<em>~ 0.375 centimeters of the snowflake in real life ~</em>

Step-by-step explanation:

Let us plan out our steps, and solve for each:

<em>1. Given the information, let us create a proportionality as such:</em>

      48       =           1      ⇒   x - centimeters of the snowflake in real life

       18                    x

<em>2. Now let us cross multiply, and solve through simple algebra for x:</em>

48 * x = 18,

x =<em> 0.375 centimeters of the snowflake in real ife</em>

Kyle got in the elevator on the 7th floor. He rode up 2 floors and then down 5 floors. Which expression represents the floor Kyl
Arte-miy333 [17]

Answer:

7+2-5=f

Step-by-step explanation:

If he starts on the 7 floor, then he is seven above ground, and that would clarify as a positive number. He then goes up 2 floors, which means we would add 2 to the original number. Going down five would mean we would subtract, because he is getting closer to zero, which is ground level. <em>F</em> represents the floor he is on now.

Hope this helps! (Brainliest please!)

The perimeter of a rectangular lot is 74 feet. The cost of fencing along the two lengths is $1 per foot, and the cost of fencing
Rama09 [41]

Answer:

340 ft²

Step-by-step explanation:

perimeter of rectangle = 2 x (L+W) = 2L + 2W = 74 .....(1)

cost of two length : $1 x 2L

cost of two width: $3.50 x 2W

($1 x 2L) + ($3.50 x 2W) = $159

2L + 7W = 159 ....... (2)

(2) - (1) ...  5W = 85

W = 17

L = (74 - 2 x 17) / 2 = 20

dimension = 17 x 20 = 340 ft²
